No, hot tubs don’t need to be plumbed in - they aren’t connected to your home’s water supply or waste system.

To fill your hot tub, you simply use a standard garden hosepipe. Once filled, the water is heated and continuously filtered inside the spa itself. Easy.

When it’s time to change the water, there’s a handy drain valve built into the side of the hot tub. You can attach a hosepipe to this valve and direct the water towards a nearby drain or suitable drainage area.

All H2O Hot Tubs models come with a comprehensive warranty which is one of the strongest in the UK.

Unlike some cheaper suppliers, all our hot tubs come with a 2 year electrical & plumbing components warranty covering pumps, heating system and controls.

All our hot tubs come with a minimum of 2 years shell surface warranty - up to 5 years on certain models!

All our hot tubs come th a minimum of 2 years shell structure warranty - up to 10 years on certain models!

You can find out more about our three warranty levels (Bronze, Silver and Gold) on our warranty page.

The main difference between a 13A plug and play hot tub and a 32A hot tub is the power supply and overall performance.

A 13A plug and play hot tub plugs into a standard household socket, making installation quicker, simpler, and more affordable. They’re a great option if you want an easy setup without additional electrical work. Many still offer powerful jets, LED lighting, and plenty of comfort for everyday relaxation.

A 32A hot tub is hardwired directly into your home’s electrics by a qualified electrician. Because it has access to more power, it can run multiple pumps, stronger jets, air blowers, and the heater all at the same time without compromising performance. These hot tubs are often larger and come with more premium features too.

For many people, a 13A model is more than enough. But if you want the strongest hydrotherapy, faster heating, and a more powerful all-round spa experience, a 32A hot tub is usually the better choice.

Yes, we do. We offer high-quality air source heat pumps with almost all of our hot tubs, helping you enjoy your spa while significantly reducing running costs.

A heat pump works by efficiently transferring heat from the air into your hot tub water, using far less electricity than a standard heater alone. Depending on the outside temperature and how you use your spa, a heat pump can reduce heating costs by up to 70%.

Hot tubs with heat pumps are especially popular with customers who use their hot tub regularly or want to enjoy it throughout the year without worrying about energy bills.

The price includes everything you need to get started with your new hot tub.

Every hot tub comes with a free insulated tapered cover (these vary in thickness by model), designed to help rainwater run off while adding an extra layer of heat retention to improve efficiency. You’ll also receive free non-slip steps with a soft rubber coating for added comfort and safer access in and out of the spa.

We also include delivery and positioning as part of the price. As long as access is suitable, our team will bring the hot tub into your garden, position it where you want it, and unwrap it to check everything is perfect before we leave.

Want a completely hassle-free setup? For a small additional charge of £199, we’ll fully fill and commission your hot tub, show you how everything works, guide you through adding chemicals, build accessories such as steps and cover lifters, and attach the cover clips too.

Most customers opt for our buy now, pay later option, allowing you to take delivery of your hot tub now and pay nothing for 6 months.

After the 6-month period, you can either settle the remaining balance in full with just a £29 admin fee, or choose to spread the cost over a longer term with repayments available from 60 to 120 months.

We offer fantastic low-rate hot tub finance at just 9.9% APR, making it easier to spread the cost of your new spa into manageable monthly payments.

It’s a flexible way to enjoy your hot tub sooner while choosing a payment option that works for you.

If you ever have a technical issue after purchase, you’re fully supported by our experienced in-house aftercare team.

Unlike some of our competitors - our support team are available on the phone and don't just hide behind emails!

All of our hot tubs include a manufacturer’s warranty, with cover varying depending on the model and components. This typically includes protection for key parts and, on many models, labour cover too for extra peace of mind.

If something doesn’t seem right, our team will help diagnose the issue and guide you through the next steps quickly and clearly.

Many questions can be resolved remotely, while more technical faults can be handled by our engineers if needed.

We keep hundreds of hot tubs in stock across our full range, which means we can often deliver much faster than people expect. Depending on your location and how busy we are at the time, delivery can sometimes be arranged in as little as 7 days.

Lead times do vary throughout the year, especially during peak seasons, but our team will always keep you updated and work with you to find the earliest suitable date.

We have our own fleet of delivery vehicles and experienced installation teams covering the whole of the UK, so whether you’re in a city centre, countryside village, or coastal town, we can usually get your new hot tub to you quickly and smoothly.

Yes, we do. We have a dedicated hot tub showroom in Nottingham, conveniently located with easy access from Junction 26 of the M1. It’s the perfect place to compare different sizes, seating layouts, features, and jet systems in person while speaking with our friendly spa specialists.

Seeing a hot tub up close can make a huge difference. You can experience the build quality, explore the features, and get a much better feel for which spa suits your space and lifestyle best.

Too far away to visit? No problem. We can arrange a personalised video call and virtually walk you around the showroom, showing you any hot tubs you’re interested in. We can also send tailored videos of specific models so you can explore the details from the comfort of your home.

The best base for a hot tub is a solid, level surface that can safely support the combined weight of the hot tub, water, and people using it. In most cases, a concrete base is the ideal option because it’s strong, stable, and long-lasting. High-quality paving slabs or a properly built reinforced patio can also work well.

Yes, a hot tub can go on decking too, but it’s important that the decking is structurally suitable and capable of supporting the weight. A filled hot tub can weigh well over a tonne, so we always recommend having timber decking professionally assessed or reinforced before installation.

The key thing is stability. A level, well-supported base helps your hot tub perform properly and protects the structure over time. If you’re unsure, our team can advise on the best setup for your garden and chosen hot tub before delivery.

Running costs are one of the most-asked questions about hot tubs. The answer is that a hot tub will use typically 7–10 kWh per day to maintain 37–38°C. This is roughly £1.50-£2.00/day for most 13A tubs and £2-3/day for larger 32A models, depending on tariff.

Usage varies with size, insulation, weather and how often you soak; add a heat pump and you could cut electricity use by up to ~70%.
