Installing a hot tub in your home is a great way to bring family and friends together and what’s more, because a hot tub can be used all year round, you will get hours of pleasure from relaxing in the warm, bubbly water.

To prepare you for your new hot tub, we have come up with a few things you need to consider before purchasing… 

  • Location
    Your new hot tub could weigh up to two tonnes when filled with water and people so it needs a solid and secure base! There are a few base options, with concrete being the most popular as it is easy to do and cost-effective. Likewise a gravel base is also cost-effective and quick to install, though do ensure that the gravel is properly compacted before placing the hot tub. Paving slabs and decking are decorative options that both look great and provide the strength needed to hold the tub securely.

    Depending on the type of spa you have chosen and the access arrangements within your home, you may need to consider how your spa will be delivered. At H2O, we offer a delivery and positioning service that will see your spa located exactly as you envisioned. In some cases, hot tubs need to be lifted into position via crane, be sure to mention any access issues when you order.

    While there is something magical about sitting outside in a hot tub in the winter, hot tubs can be used indoors. If you intend to fit one inside, consider the room’s ventilation, the steam from the water and users can create a lot of moisture so be sure your room is able to cope. 


  • Installation
    While your new hot tub does not require any plumbing (it is filled via a hosepipe), it will require access to an electrical supply. For this you will need a qualified electrician, the spa you choose will come with fitting instructions that will detail everything your electrician needs to consider.

    Once your hot tub has been installed, you will be able to enjoy it as and when you choose. Depending on the amount you use it, you can expect your hot tub to add around £20 to £40 to your monthly electricity bill.


  • Maintenance
    In terms of maintenance, your hot tub will require that you regularly check the water’s pH level, check it twice a week, aiming for a pH of around 7.4. There are a range of chemical starter packs which include everything you need to keep your water sanitary, including test strips and filter cleaner. Once a week your filter will need a thorough rinse, this will help remove dirt and prevent hair from clogging it up. Once a month give the filter a clean with a filter cleaner, soaking it for around 15 minutes and every two months let the filter soak overnight in a chemical cleaner. Keeping on top of cleaning your filter will not only help keep the hot tub working at optimum levels but will prolong the life of the filter.  A complete drain and clean of the shell every three to four months will help remove any build-up of dirt and keep the water fresh and clean.

There is a wide range of hot tubs available, from two seaters that are perfect for smaller spaces to larger ones able to accommodate up to seven people. For more details on choosing the right hot tub for your space or for help and advice on installation, call the H2O Hot Tubs team.
