Single Ended Whirlpool Baths

A single ended whirlpool bath is the format most UK homes already have, upgraded with jets. Taps and waste sit at one end, the back slopes at the other, and the jets face the bather for a firm hydro-massage. Because the layout matches a standard straight bath, it is the simplest whirlpool to fit as a like-for-like replacement, and it makes the most of the space in a one-person or family bathroom.

This page sets out the sizes, the jet options, and why a single-ended bath is often the practical choice when you are swapping an existing bath. For the full range of shapes, start at the whirlpool baths pillar, and if two-person bathing matters more than an easy swap, compare the double ended whirlpool baths page.

Why single-ended suits most homes


The single-ended shape wins on simplicity. Your taps and waste already sit at one end, so a like-for-like swap rarely needs the plumbing moved. The sloped back supports one bather comfortably, and all the bathing length goes to that person rather than being shared, so even a 1700mm bath feels roomy for one. For the common job of turning a tired straight bath into a spa bath, this is the least disruptive route.

It also tends to be the better value. Single-ended baths are the volume shape, so the range is wide and the prices competitive across both jet systems. If your household is one or two people who bathe separately, you gain little from a larger double-ended bath and pay more to fill it.

Sizes and fit


Single-ended whirlpool baths cover the full run of standard UK sizes, so you can match your existing bath closely.


Standard lengths

1700mm by 700mm is the default and the easiest replacement. 1800mm adds legroom where the wall is long enough. For shorter walls, 1500mm and 1600mm models keep the single-ended layout in a smaller footprint, and the small whirlpool baths range covers the most compact options.


Matching your existing bath

Measure your current bath and the recess before ordering. If the new bath matches the length and width, the swap is straightforward and the tiling around it stays largely intact. A different size means adjusting the surround, so a like-for-like match saves time and money on the fit.

Jet systems


A single-ended bath places all its jets to serve the one seating position, so the massage is focused rather than shared.


Water jets

Water jets in the sides target your back, hips and legs with a firm, directed stream. Because there is only one bather to serve, a single-ended bath concentrates the water massage where you sit.


Air jets

Air jets in the base lift warmed bubbles up through the water for a gentle all-over soak. In a single-ended bath the air system fills the space around one person evenly.


Combination and extras

A combination system gives you both, run together or apart. An inline heater holds the temperature during longer soaks, and colour-changing LED lighting adds a spa feel. The guide on things to consider when getting a whirlpool bath covers how to match the system to how you actually bathe.

Installation as a like-for-like swap


The single-ended bath is the easiest whirlpool to install because the plumbing usually stays where it is. Your plumber connects the water and waste at the existing end, and a qualified electrician wires the pump through a fused spur and isolator to current bathroom regulations. Leave a removable access panel to reach the pump and heater. That is the one addition over a plain bath swap, so plan the panel into the surround.

Check the floor is level and solid under the recess, since the frame needs a true base to sit the bath correctly. Beyond the electrics and the panel, fitting a single-ended whirlpool bath is much the same job as fitting any straight bath.

Running costs and cleaning


A single-ended bath at standard size holds a normal volume of water, so it costs no more to fill than the bath it replaces. The pump adds a small amount of electricity per soak, and a heater, where fitted, holds temperature rather than heating from cold.

For cleaning, rinse the system after use and run a whirlpool cleaner through the pipework every few weeks. Wipe the acrylic with a non-abrasive cream and warm water. The routine is quick and keeps the jets and finish in good order.

Delivery across the UK

How to choose your single ended whirlpool bath


Measure your existing bath and match the size for the easiest swap. Pick the jet system for the massage you want, water for a firm back-and-leg feel, air for gentle all-over bubbles, or both. Add a heater and lighting if you plan long soaks. Confirm the electrical supply and access panel with your fitter. If you want the reinforced Carronite base, the Carron whirlpool baths range includes single-ended models, and our own Lisna Waters whirlpool baths line offers strong value across the standard sizes.

Single ended sizes and dimensions


Single-ended baths cover the full run of UK sizes, which is part of why they are the easiest to fit: whatever your recess measures, there is usually a close match. The standard is 1700mm by 700mm, and it replaces most existing baths cleanly. Where the wall runs longer, 1800mm adds legroom, and a few models reach 700mm to 800mm wide for a roomier soak. Shorter walls are covered by 1500mm and 1600mm baths, with the most compact options in the small whirlpool baths range.

All the bathing length in a single-ended bath serves one person, since only one end is sloped. That makes even a 1700mm bath feel generous for a single bather, with a longer flat zone than a double-ended bath of the same size. Check the internal length from the sloped back to the tap end so you know the real space you lie in.

Measure your existing bath and the recess in several places, work to the smallest width, and match the new bath as closely as you can. A like-for-like size keeps the surrounding tiling largely intact and turns the job into a straightforward swap.

Taps, panels and waste


Single-ended baths are drilled for taps at the tap end, or supplied undrilled for wall-mounted taps, and they come without taps so you can match the suite. The end drilling is the standard arrangement most bathrooms already use, which is another reason the swap is simple. Confirm the tap hole configuration when you order.

A front panel boxes in the pump and pipework, with an end panel where a side is exposed, and both should come off without lifting tiles so the jets can be serviced. The waste and overflow are specified separately. Because a single-ended bath is filled and drained often, a good quality waste is worth the small extra outlay.

Who a single ended whirlpool bath is for


This is the bath for the most common job in the range: replacing a tired straight bath with a spa bath, with the least disruption and the best value. It suits households of one or two people who bathe separately, and any bathroom where the plumbing already sits at one end and you would rather not move it.

If you want to share the bath, a double ended whirlpool bath is the better shape. If the bath is the centrepiece of a bigger refit, a whirlpool freestanding bath makes more of the room. For most replacements, though, the single-ended bath is the sensible default, and the full whirlpool spa baths collection lets you confirm that against the alternatives.

The simplest upgrade in the bathroom


Of all the ways to improve a bathroom, swapping a tired straight bath for a single-ended whirlpool bath is one of the least disruptive and most rewarding. The plumbing stays where it is, the tiling around a matched size stays largely intact, and in return you get a hydro-massage every time you fill the bath. It is the upgrade that changes how the room feels without turning it into a building site.

It also suits the widest range of budgets, because single-ended baths are the volume shape. Our own Lisna Waters whirlpool baths line covers the value end, while the Carron whirlpool baths range offers a British-made shell and a long guarantee for buyers who plan to keep the bathroom for years. Either way, the fit is the same straightforward swap.

When you are ready, we ship single ended whirlpool baths across the UK with free delivery over £500 and a next-day service on many models, so the bath arrives in time for your fitter. Match your existing bath size, confirm the pump wiring and the access panel with your installer, and the job is close to a like-for-like change. If you are unsure which size or jet system suits how you bathe, our team matches baths to bathrooms every day and is happy to help you choose.

Frequently asked questions


Is a single ended whirlpool bath easy to fit as a replacement?

Yes, it is the easiest whirlpool to fit because the taps and waste stay at the existing end. The only addition over a plain bath swap is the pump wiring and a service access panel.

What is the difference between single and double ended?

Single-ended has taps at one end and a sloped back at the other, built for one bather. Double-ended centres the taps and slopes both ends for two. Single-ended is the simpler swap; double-ended is the shared soak.

What size single ended whirlpool bath is standard?

1700mm by 700mm is the UK standard and the easiest replacement. 1800mm adds legroom, and 1500mm to 1600mm models suit shorter walls.

Can I get a single ended bath with both jet types?

Yes. Combination models run water and air systems together or separately, so you can switch between a firm massage and gentle bubbles in the same bath.

Do I need to move my plumbing for a single ended whirlpool bath?

Usually not. The taps and waste sit at one end, matching the layout most bathrooms already have, so a like-for-like swap keeps the plumbing where it is. The only addition is wiring the pump and leaving a service access panel.

What is the best size for a family bathroom?

1700mm by 700mm is the standard family size and the easiest replacement. If the wall is long enough, 1800mm adds legroom for taller users. Match your existing bath where you can to keep the surrounding tiling intact.

Can a single ended whirlpool bath have a shower over it?

A straight single-ended bath is narrow at the tap end, so it is not ideal for showering. If you need to shower over the bath, a whirlpool shower bath with a widened end is the shape designed for it.

Which brand of single ended whirlpool bath should I choose?

For value, our own Lisna Waters whirlpool baths line gives the same jets for less. For a British-made shell with the reinforced Carronite base and a long guarantee, the Carron whirlpool baths range is the step up.

How long does it take to fit a single ended whirlpool bath?

For a like-for-like size, a competent installer usually fits one in a day, since the plumbing stays at the existing end. The extra steps over a plain bath are wiring the pump through a fused spur and isolator, and setting a removable access panel. Allow more time if the surround or tiling needs adjusting for a different size.
