How to Find Your Hot Tub Brand and Model

Finding your hot tub brand and exact model is one of the easiest ways to simplify the replacement-cover process. If the model can be identified confidently, you may be able to use existing model specifications instead of measuring every dimension manually.

The challenge is that spa labels are not always obvious, especially on an older hot tub or a spa purchased with a property.

This guide explains how to find your hot tub brand and model, where to look for the serial plate, what information to record, and what to do if the original model name is missing.

Why Does the Exact Hot Tub Model Matter?

The brand alone is usually not enough to identify the correct replacement spa cover.

A manufacturer may have produced dozens or even hundreds of models with different:

• lengths and widths;
• corner radii;
• spa shapes;
• model years;
• seat layouts;
• and cover configurations.

For example, two spas from the same manufacturer can look very similar while requiring different replacement covers.

Identifying the exact model helps reduce uncertainty and gives you a better starting point when checking dimensions and fit.

Where Can You Find the Hot Tub Brand?

The manufacturer name is often the easiest information to identify.

Look for branding on:

• the spa cabinet;
• the control panel;
• the acrylic shell;
• the equipment access panel;
• the original cover;
• the owner's manual;
• or purchase paperwork.

Common spa manufacturers include Jacuzzi, Wellis, Hot Spring, Sundance, Bullfrog, Caldera, Master Spas, Arctic Spas, Hydropool, Cal Spas, Coast Spas, and many others.

Once you know the manufacturer, you can browse the SpaCoverLabs brand database and narrow the search to models from that brand.

Where Is the Hot Tub Model Number?

The model name or number is commonly found on a manufacturer label or serial plate attached to the spa.

The exact location varies by manufacturer, but common places include:

• inside the equipment compartment;
• behind the removable cabinet panel;
• near the control box;
• on the spa frame;
• on an identification label attached to the cabinet;
• or in the original owner's documentation.

For example, Jacuzzi states that on many of its hot tubs the serial number is located in the equipment bay, on top of the load box. You can check the manufacturer's own instructions for your specific spa if the label is difficult to locate.

What Is a Hot Tub Serial Plate?

The serial plate is an identification label attached to the spa by the manufacturer.

Depending on the brand, it may contain:

• manufacturer name;
• model name or model number;
• serial number;
• production information;
• electrical specifications;
• certification information;
• and other technical details.

For replacement-cover identification, the most useful information is usually the manufacturer, model, and serial number.

Take a clear photo of the full label before closing the equipment compartment.

What Is the Difference Between a Model Number and a Serial Number?

The model identifies the type of spa.

The serial number identifies the individual spa or production unit.

For example:

Information	Purpose
Brand	Identifies the manufacturer
Model	Identifies the spa design or product
Serial number	Identifies the individual spa or production unit
Production year	May help distinguish different model revisions

The serial number can be especially useful when a manufacturer has changed specifications while keeping the same or similar model name.

Why Can the Model Year Matter?

Spa manufacturers sometimes update a model without changing its main product name.

A later version can differ in:

• dimensions;
• corner shape;
• cabinet design;
• controls;
• seat configuration;
• or other construction details.

This is why identifying only the brand and model name may not always be enough.

If your measured spa dimensions differ from the specifications stored for a model, the production year or revision may explain the difference.

Step 1: Check the Spa Cabinet

Start by walking around the outside of the hot tub.

Look for:

• brand badges;
• model labels;
• small metal plates;
• printed stickers;
• or labels near removable cabinet panels.

Do not remove any electrical covers or components unless the spa manufacturer's instructions say it is safe to do so.

You are usually looking for an identification label rather than accessing electrical equipment.

Step 2: Check the Equipment Compartment

If the outside of the cabinet does not show the model information, check the main equipment access area.

This is where many manufacturers place the serial or identification plate.

The label may be:

• attached to the inside of the cabinet;
• fixed to the frame;
• near the control box;
• or positioned on another visible component within the equipment bay.

Manufacturer-specific locations vary, so consult the owner's manual if available.

Step 3: Check the Owner's Manual

If you still have the spa documentation, this can be one of the easiest places to confirm the model.

Look at:

• the cover page;
• warranty registration;
• installation documents;
• service records;
• and purchase invoices.

Some manuals cover an entire model range rather than one specific spa, so confirm that the document actually identifies your individual model.

Step 4: Check Purchase or Service Records

Previous invoices can contain useful information, particularly if the spa has been serviced by an authorised dealer.

Look for:

• model name;
• serial number;
• production year;
• or original dealer information.

If the spa came with a home you purchased, the previous owner may also have left manuals, receipts, warranty documents, or service paperwork.

Step 5: Search the SpaCoverLabs Model Database

Once you know the brand or model name, search the SpaCoverLabs spa model database.

For supported models, the database may contain information such as:

• model name;
• brand;
• shape;
• cover dimensions;
• corner radius;
• and related model specifications.

Compare the stored information with the actual spa before ordering.

Finding the model is the starting point, not a reason to ignore obvious differences.

What If You Know the Brand but Not the Model?

This is common.

Start by browsing the models listed under that manufacturer.

Then compare your spa with:

• overall shape;
• approximate dimensions;
• number of seats;
• lounger position;
• control-panel location;
• corner shape;
• and other visible features.

This can help narrow the possibilities, but do not select a model based only on a similar photograph if several models look alike.

Use serial information or measurements where possible.

Can You Identify a Hot Tub Model from Its Shape?

Sometimes, but shape alone is rarely enough.

A square or rectangular spa with rounded corners can resemble many other models.

Shape becomes more useful when combined with:

• dimensions;
• seat layout;
• number of headrests;
• control-panel position;
• waterfall location;
• speaker positions;
• and cabinet details.

SpaCoverLabs model pages may include shape information that can help you compare your spa with the listed specification.

Can You Identify a Hot Tub from a Photo?

A photograph can often help narrow down the possibilities, especially when combined with a brand name, serial plate, or approximate measurements.

Useful photographs include:

• a full view from above;
• the spa without the cover;
• the control panel;
• the cabinet and brand badge;
• the serial plate;
• and the existing cover fitted to the spa.

If you cannot identify the model confidently, you can send photos to the SpaCoverLabs Team. The SpaCoverLabs contact form specifically allows customers to upload photographs of the spa, existing cover, or serial plate to help with identification.

What Photos Are Best for Model Identification?

Try to provide several clear photos rather than one close-up.

The most useful set is:

1. A full photograph of the spa from above.
2. A photograph showing the complete cabinet.
3. A close-up of the control panel.
4. A clear photograph of the serial plate.
5. A photograph of the existing cover on the spa.

If possible, also provide the approximate overall length and width.

This combination gives much more context than a single corner or logo photograph.

What If the Serial Plate Is Missing?

Do not assume the spa cannot be identified.

Older identification stickers can fade, become damaged, or disappear during repairs or cabinet replacement.

If the serial plate is missing, collect as much alternative information as possible:

• brand name;
• approximate age;
• overall dimensions;
• spa shape;
• seat layout;
• control-panel design;
• number and position of headrests;
• waterfall or speaker locations;
• and photographs.

Then compare the information with models from the relevant manufacturer.

What If the Brand Badge Is Missing?

This can make identification more difficult, but there are still clues.

Check:

• the control panel for a manufacturer's name;
• the equipment label;
• pump or control-system documentation;
• old service invoices;
• the original cover;
• and paperwork left with the spa.

Be cautious when using the control-system manufacturer as proof of the spa brand. Many hot tub manufacturers use components supplied by other companies.

A control-system brand is therefore not necessarily the same as the hot tub manufacturer.

Can the Existing Cover Tell You the Model?

Sometimes.

An original replacement cover may have:

• a manufacturer label;
• product code;
• model reference;
• or dealer information.

However, the cover may itself be an aftermarket replacement that was manufactured from measurements rather than a spa model.

Use information from the old cover as supporting evidence rather than your only source.

What If You Bought the Spa Second-Hand?

Used hot tubs often arrive without complete paperwork.

Use this process:

1. Look for the manufacturer badge.
2. Check the equipment compartment for a serial plate.
3. Photograph the spa from above.
4. Measure the overall dimensions.
5. Check the control panel.
6. Search the manufacturer's model history where available.
7. Compare possible models with the SpaCoverLabs database.

If you still cannot identify it, you can order a replacement cover using measurements rather than a model.

What If Your Spa Model Is Discontinued?

A discontinued model can still have a replacement cover available.

The spa itself does not stop needing maintenance simply because the manufacturer no longer sells that model.

If SpaCoverLabs already has specifications for the model, you may still be able to configure the replacement from the database.

If no model information is available, measure the spa itself using the SpaCoverLabs Measuring Guide.

What If the Model Name Has Changed?

Some manufacturers use similar names across different product generations or markets.

A model can also be renamed or included within a broader series.

If you find several similar names:

• compare dimensions;
• check the production year;
• compare serial information;
• look at seat layout;
• and review the exact spa shape.

Do not select a cover simply because the name is close.

What If the Database Dimensions Do Not Match Your Spa?

Stop and investigate before ordering.

Possible explanations include:

• the wrong model was selected;
• the manufacturer changed the design between model years;
• your spa is a regional variation;
• the measurement was taken incorrectly;
• or the stored specification requires review.

Measure the spa again and compare more than one dimension.

If the difference remains, contact SpaCoverLabs with the serial plate, photos, and measurements.

Should You Measure the Spa Even If You Know the Model?

It is sensible to compare the model specification with the actual spa before placing a custom order.

You may not need to perform a complete manual measurement for every supported model, but obvious differences should never be ignored.

If you are unsure whether to rely on model data or your existing cover, read Should You Measure Your Spa or Your Existing Hot Tub Cover?

What Measurements Are Most Useful for Model Verification?

If you need to confirm whether a model match is correct, start with:

• overall length;
• overall width;
• shape;
• corner radius;
• and visible spa layout.

For rounded spas, corner radius can be particularly helpful when several models have similar overall dimensions.

Use our guide to measuring a hot tub cover corner radius if necessary.

Do Not Identify a Spa from Dimensions Alone

Dimensions are useful, but they are not always unique.

Many hot tubs share similar overall sizes.

For example, several unrelated spas may all measure approximately:

• 200 × 200 cm;
• 210 × 210 cm;
• or another common footprint.

Combine dimensions with:

• brand;
• serial information;
• corner radius;
• shape;
• and spa features.

Does the Exact Model Matter for Corner Radius?

Yes.

Two spa models with similar overall dimensions can have noticeably different corner curves.

This affects how the replacement cover follows the perimeter.

If you identify a possible model but the corner shape clearly does not match, investigate before ordering.

For manual verification, follow the corner-radius guide.

What If You Cannot Identify the Spa at All?

You can still order a custom replacement cover.

Model identification makes the process easier, but it is not mandatory when accurate measurements can be provided.

Use the SpaCoverLabs Measuring Guide to determine:

• length;
• width;
• shape;
• corner radius;
• skirt length;
• and other required details.

Then configure the replacement using the measured specifications.

Search by model first. Measure when necessary.

How Does Model Identification Help When Replacing an Old Cover?

An ageing cover can become an unreliable measuring reference.

It may be:

• warped;
• waterlogged;
• stretched;
• shrunk;
• sagging;
• or incorrectly sized from the beginning.

If you can identify the exact spa model, you gain another source of information instead of depending entirely on the old cover.

How Do You Find the Correct Replacement Cover Once You Know the Model?

1. Search the Brand

Go to the SpaCoverLabs brand directory and select the manufacturer.

2. Find the Model

Search or browse the models listed for that brand.

3. Review the Model Specifications

Compare the displayed:

• dimensions;
• shape;
• corner radius;
• and other available information

with your actual spa.

4. Resolve Any Differences

If the specifications do not match, do not continue simply because the model name appears correct.

Check the serial information, measurements, and model year.

5. Configure the Replacement Cover

Once the correct model and specifications are confirmed, continue with the available cover options.

Frequently Asked Questions

Where do I find the model number on my hot tub?

The model number is commonly found on an identification or serial plate inside the equipment compartment, behind a cabinet access panel, on the spa frame, or in the original owner's documents. Exact locations vary by manufacturer.

Where is the hot tub serial number?

The serial number is usually printed or engraved on the manufacturer's identification label. For many spas, this is located inside the equipment bay or behind the main access panel.

Can I identify my hot tub from the serial number?

Often, yes. The serial number can help a manufacturer or specialist confirm the exact product or production revision, especially when several versions share a similar model name.

Can I identify my spa from a photo?

Photos can help narrow the possibilities, particularly when they show the spa from above, the control panel, cabinet, serial plate, and existing cover. Combine photographs with measurements or serial information where possible.

What if my hot tub has no model label?

Look for manuals, invoices, service paperwork, control-panel branding, or an identification plate in the equipment compartment. If no label can be found, use photographs and measurements to help identify the spa.

What if I know the brand but not the model?

Browse the models for that manufacturer and compare dimensions, shape, seating layout, control-panel position, and other identifying details. Do not select a model solely because the photograph looks similar.

Can SpaCoverLabs identify my hot tub from a photo?

SpaCoverLabs allows customers to send photos of the spa, existing cover, or serial plate to help with model identification and replacement-cover enquiries.

What if my model is not in the SpaCoverLabs database?

You can still order a custom replacement cover by measuring the spa. Follow the SpaCoverLabs Measuring Guide for the required dimensions and shape information.

What if the model dimensions do not match my spa?

Recheck the measurements, exact model, production year, and serial information. If the difference remains, contact SpaCoverLabs with photos and measurements before ordering.

Do I need to know my spa model to order a replacement cover?

No. Knowing the model can simplify the process, but a custom cover can also be configured from accurate spa measurements when the exact model cannot be identified.

Find Your Hot Tub Brand and Model Before Measuring

Finding your hot tub brand and model can make ordering a replacement cover much simpler.

Start with the manufacturer badge, serial plate, equipment compartment, owner's manual, and purchase or service records.

Once you have a likely model, compare it with your actual spa rather than relying on the name alone.
