About Our Plastic Hot Tub Base

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 spilled 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 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.

Installation Guide

Can I use the ‘hot tub base panels’ under the inflatable hot tub.

We do not recommend this, as the ‘hot tub base panels’ can sometimes have sharp edges that can catch on the soft material of the inflatable hot tub.

What do I need under my grid?

We recommend you prep the grid with compact hard base (type 1 or type 3), sand and membrane.

Do I need pegs?

Only areas that have a gradient over 12% need pegs.

How do I know which side to put down?

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


How many grids are there per pack?

In each pack there are 4 grids.

How will order be sent?

Our X-Grid Panels are 33cm x 33cm. For ease, speed, and efficiency of shipping, we pack a maximum of 24 panels inboxes and send through courier network. Greater quantities than 180 panels will be delivered through the Palletways network.

How are the products packaged?

We take great care when packaging your order to ensure that our products reach you in the best possible condition. In addition, we are always trying to be more sustainably friendly therefore try to minimize the amount of plastic packaging we use around our products and use recycled packaging. If your product arrives broken, we will send replacements within 3-5 working days.

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

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

What is the pricing of shipping based off?

Our shipping is based on the postcode and weight of the order. You can see the price of your shipping before you purchase by going into the checkout and filling in ‘calculate shipping’. We endeavor your product to be delivered within 3-5 working days.

Where can I find the instructions?

Instructions can be found on the ‘downloads’ tab at the bottom of the product’s page. In addition, more information on installation can be found through our blogs and YouTube videos.

Does this come with pins or membrane?

It comes with neither pins or membrane, you will need to buy this separately.

Do the hot tub base panels need gravel or is it strong enough without it?

The hot tub base panels are strong enough without gravel. The gravel can be used to compact and secure even more and for decorative use.
