Wet Room & Bathroom Renovation FAQs for Poole Homes

If you've been putting off replacing a tired bathroom or converting to a wet room, you're not alone. It's one of the bathroom and wet room renovation projects we get asked about most across Poole, Sandbanks and the wider BCP area — and also one where homeowners tend to have the same handful of questions before they'll commit. Coastal humidity, older housing stock, and a market where a good bathroom genuinely moves the needle on value all make this a project worth getting right first time.

Below we've answered the questions we hear most often from Poole homeowners considering a bathroom or wet room renovation, from cost through to whether it's even suitable for your property.

How much does a wet room or bathroom renovation cost in Poole?

For a standard family bathroom refit — new suite, tiling, flooring and updated electrics — most Poole projects land somewhere between £6,000 and £12,000, depending on fittings and whether any pipework needs moving. A full wet room conversion, which involves lowering or building up the subfloor, tanking the entire room, and fitting a level-access shower area, typically runs from £9,000 to £18,000. Period and coastal properties around Poole Harbour and Sandbanks often sit at the higher end, simply because older joists, solid floors, or previous damp issues need addressing before any waterproofing goes in.

The honest answer is that cost varies more with what's underneath your existing bathroom than with the tiles and taps you choose. We always survey before quoting, because a like-for-like refit and a full wet room conversion are very different jobs even when the room looks the same size on paper.

How long does a bathroom or wet room project actually take?

A straightforward bathroom refit usually takes one to two weeks from strip-out to first use. A full wet room conversion, with tanking, floor build-up, and drying time for waterproofing membranes, is closer to two to three weeks. Add a few extra days if we're relocating a soil pipe, moving a stud wall, or if underfloor heating is going in alongside the shower — all common upgrades on Poole projects, particularly in the older terraces around Parkstone and Ashley Cross.

We'd rather give you a realistic timeline upfront than a fast one that slips halfway through, especially if your household only has one bathroom.

Do I need planning permission or building regulations sign-off?

Most bathroom and wet room work doesn't need planning permission, since it's an internal change of use rather than an extension to the property. Building regulations are a different matter. Any electrical work — extractor fans, shaver points, underfloor heating controls — falls under Part P and needs to be certified by a qualified electrician or notified to BCP Council's building control team. Waterproofing and tanking in a wet room also needs to meet current regs, particularly around ventilation and drainage falls, so the room performs properly for years rather than just looking good on handover day.

If you're in a flat or a listed or conservation-area property (there are pockets of these around Poole Old Town and the Quay), it's worth checking with us early, as leasehold consent or heritage considerations can occasionally add a step to the process.

Is a wet room suitable for my Poole property?

Wet rooms work in almost any property, but older Poole homes — particularly 1930s semis and Victorian terraces — sometimes have suspended timber floors rather than solid concrete, which changes how we approach waterproofing and structural support. It's entirely doable; it just needs the right build-up (usually a combination of plywood decking, a tanking system, and sometimes a shallow steel or timber upstand) rather than assuming every floor behaves the same way.

Ground-floor rooms with solid concrete floors are generally the simplest conversion. First-floor wet rooms are increasingly common too, especially in ensuite conversions, but they do need careful attention to floor structure and, in some cases, discreet soundproofing so water noise doesn't travel to the room below. We're also seeing more requests for accessible, level-access wet rooms from homeowners planning ahead for aging in place — these follow the same waterproofing principles but with wider door openings and support rail fixing points built in from the start.

Will I need to move out, and how much disruption should I expect?

If it's your only bathroom, we'll always talk through options before starting — some households choose to stay and use a temporary shower or nearby facilities for the noisier days, others prefer to time the work around a holiday. You won't need to move out of the house itself; the disruption is contained to the bathroom and the immediate access route for materials, and we sheet and protect hallways and stairs as standard. Dust and noise are heaviest during strip-out and floor preparation, typically the first two to three days, and much quieter from first fix onwards.

Wet room, walk-in shower, or traditional bathroom — which adds the most value?

For most Poole homes, a well-finished wet room or level-access walk-in shower room tends to appeal most broadly to buyers, particularly in properties aimed at downsizers or those wanting a lower-maintenance coastal second home. That said, if your property only has one bathroom and no separate WC, most buyers still expect at least one bath somewhere in the house, so a family home may do better keeping a bath in place and adding a separate shower room or ensuite as a wet room. We'll usually talk through your household's actual day-to-day use alongside resale before recommending either direction — the right answer depends more on your specific property and buyer pool than on any single trend.
