About Our Plastic Hot Tub Base Kit

Manufactured here in the UK and made from 100% recycled plastic, our eco-friendly bases are designed with an interlocking slot and peg system that makes laying the foundation for your hot tub incredibly easy. The open structure of each panel allows any rain or spilt water to drain away naturally from your spa which harder surfaces such as concrete cannot do. Whilst being easy to lay and eco-friendly our bases are incredibly strong, we had the base tested by Lloyds British and it was able to withstand up to 420 tonnes per square metre. Due to being made from recycled plastic, our base is UV & weather resistant which means it will not break down or rot like traditional bases may do after some time.

Will Your Base Work Under My Hot Tub?

Yes, our base works with all models and makes of hot tubs and spas. This particular foundation is perfect for spas with a rectangle footprint measuring up to 297 x 231cm. We do have a large range of other bases available. You can see specific makes and models in our “compatibility” tab above. If you do not see your hot tub mentioned, use the measurements provided on each product to see if this base or another size would be suitable for your spa. If you cannot find one, you can leave us a message or live chat us to discuss your specific needs.

ASK A QUESTION

What are your hot tub bases suitable for?

Our plastic hot tub bases are incredibly effective and versatile. They are a suitable foundation for almost all hot tubs and swim spas. Please contact us if you are unsure of compatibility.

Can I use the plastic hot tub base panels under an inflatable hot tub.

We do not recommend this, as the plastic tub base panels can sometimes have sharp edges which may catch on the soft material and potentially damage the inflatable hot tub. We do have inflatable hot tub bases, which are perfect for supporting your blow up hot tub.

What sub-base do I need under my hot tub base?

We recommend you prepare the ground below your base with approximately 100mm of a compact hard base (type 1 or type 3), a weed-suppressing membrane and sand to level.

What is the difference between compact hard base type 1 or type 3?

Compact hard base, type 1 is much finer and can occasionally dust while the compact hard base, type 3 is larger and more permeable.

Can I put the base straight onto grass or soil?

We recommend not installing directly onto grass or soil but instead, install onto a compact hard base as it creates a sturdy, even base. Soil or grass can and will most likely will absorb water leading to sinking and creating an uneven sub-base for your spa base.

Can your plastic bases be installed on to concrete slabs/pads?

Yes, they can be installed onto concrete slabs or pads as long as the existing ground is strong and level. The base will allow airflow under your spa and elevate it away from any potential surface water.

How much gravel or aggregate should I use to fill my base?

Approximately 8kg of gravel or aggregate is required to fill each panel, or 72kg per m².

What size gravel should I use?

We recommend using anything up to 20mm in size.

Does the base need to be filled with gravel?

Our bases are more than strong enough without a gravel fill, able to withstand up to 420 tonnes per sqm. The gravel can be used to compact and enforce even more whilst also being a decorative finish.

Does this product come with pins or membrane?

Yes, our hot tub base kits come with pins and a sheet of membrane.

Can the plastic base panels be cut to size?

Yes they can be cut and we recommend doing so with a fine tooth saw.

Do I need pegs or anchors to secure my base?

Pegs and anchors to secure you base are only necessary when installing on areas which have a gradient over 12%.

How do I know which side of the panel to put down?

The bottom of the base has ‘X-Grid’ written on it, indicating the face you put on the ground.

Can the base panels be stacked on top of each other?

No, they are not designed to be stacked.

Where can I find installation instructions?

Install guides can be found on the ‘downloads’ tab. In addition, more information on installations can be found through our blogs and YouTube videos.

Can I create a grass base with the use of your hot tub base?

Yes, grass can grow in the panels cells when correctly filled with soil and seed.

Do your plastic hot tub bases have a warranty?

Yes, our bases have a 10 year manufacturer warranty.

Can I be guaranteed the same colour all throughout my product?

Our products are new generation, manufactured entirely from post-consumer recycled plastic; this means you may occasionally find very slightly different shades of colour.

How much is delivery?

The cost for delivery can be seen when you add your product to basket and at checkout.
