How Much Does a New Bathroom Cost in Portsmouth?

The Honest Answer: It Depends

We know that's not what you want to hear when you're trying to plan a budget. But bathroom costs genuinely vary quite a lot depending on the size of your room, the quality of fixtures you choose, and how much of the existing layout you want to change. What we can do is give you a proper, detailed breakdown based on the bathrooms we've actually fitted across Portsmouth and the surrounding areas.

At Blimp Plumbing, Fraser has fitted everything from compact en-suites in Southsea terraces to large family bathrooms in detached houses in Waterlooville. Here's what you can realistically expect to pay in 2025.

Cost Breakdown by Budget Level

Budget-Friendly Refresh: £2,500 - £5,000

This is a like-for-like replacement — new bathroom suite in the same positions, basic tiling, and freshening everything up. It's perfect if your layout works fine but everything is looking tired.

What you get:

• New toilet, basin, and bath or shower tray
• Basic mixer taps
• Ceramic wall tiles (part-height) and vinyl or basic porcelain floor
• Standard chrome towel rail
• New silicone and sealant throughout

What you don't get:

• Moving any plumbing positions
• Full floor-to-ceiling tiling
• Underfloor heating or premium fixtures

This level works well for landlords updating rental properties or anyone on a tighter budget who still wants a clean, modern bathroom. We fit a lot of these across Gosport and Fareham rental flats.

Mid-Range Renovation: £5,000 - £10,000

This is our most popular option and where most homeowners in Portsmouth end up. You get a genuinely lovely bathroom with quality fixtures and a more personalised design.

What you get:

• Quality bathroom suite (wall-hung toilet, vanity basin unit)
• Thermostatic mixer shower with rainfall head, or a bath-shower combo
• Full floor-to-ceiling tiling with quality porcelain or ceramic tiles
• Heated towel rail
• LED mirror cabinet or backlit mirror
• New extractor fan with humidistat
• Potential for minor layout changes (moving the basin, for example)

Typical cost split:

• Materials and fixtures: £2,000 - £4,500
• Labour (plumbing, tiling, fitting): £3,000 - £5,500

High-End Renovation: £10,000 - £20,000+

This is the full works — designer fixtures, premium finishes, and no compromises. Think walk-in wetroom showers with frameless glass, underfloor heating, natural stone tiling, bespoke vanity units, and digital shower controls. At this level, you may also be looking at structural work — combining a bathroom and separate toilet, or converting a bedroom into a large en-suite.

What Affects the Cost Most?

Some factors have a bigger impact on the final bill than others. Here's what really moves the needle:

Moving the Plumbing

Keeping your toilet, basin, and bath or shower in roughly the same positions saves a significant amount. The moment you want to move the toilet to the opposite wall or relocate the shower, the labour costs increase because we need to re-route waste pipes and water feeds. Moving a toilet is particularly costly because the soil pipe is larger and has strict gradient requirements.

The Size of the Room

A compact en-suite (around 3-4 square metres) will cost less than a large family bathroom (6-8 square metres) simply because there's less tiling, less pipework, and fewer fixtures. Most Portsmouth terraced houses have bathrooms at the smaller end, which is actually a plus for the budget.

Tiling Choices

Tiles are one of the biggest variables. Basic white ceramic tiles from a trade supplier might cost £15-£20 per square metre. Premium porcelain tiles from a showroom can easily be £60-£100+ per square metre. And intricate patterns or mosaics take longer to fit, so labour costs go up too.

Waterproofing and Prep Work

If your bathroom has damp, rotten floorboards, or crumbling plaster behind the old tiles, this prep work adds cost but is absolutely essential. Skimping on waterproofing behind a shower is a false economy — we've seen water damage that cost more to fix than the bathroom renovation itself.

Hidden Costs to Watch Out For

Budget for potential extras: skip hire (£200-£350), asbestos removal in older Portsmouth and Havant properties (£300-£800), electrical work for new sockets or extractor fans (£150-£400), and re-plastering after tile removal (£300-£600). We flag these during our free survey so there are no surprises.

How to Get the Best Value

Based on our experience fitting bathrooms across Portsmouth, Fareham, Gosport, Havant, Waterlooville, and Chichester, here are our top tips for getting the most bathroom for your money:

• Keep the layout — Working with the existing plumbing positions saves hundreds on labour.
• Invest in the things you touch — Spend more on the shower, taps, and toilet. Go cheaper on tiles if needed.
• Don't over-tile — Half-height tiling with painted walls above is a legitimate design choice that saves money and looks great.
• Buy ex-display or end-of-line — Bathroom showrooms in Fareham and Havant regularly sell display models at big discounts.
• Get three quotes — But don't just go for the cheapest. A bathroom is a long-term investment, and poor installation will cost you more in the long run.

How Long Does It Take?

Timelines depend on the scope, but here's a rough guide:

• Budget refresh: 4-6 working days
• Mid-range renovation: 6-8 working days
• High-end renovation: 8-12 working days

We plan around your schedule as much as possible and always give you a clear timeline before we start. We know being without a bathroom is a pain, so we work efficiently to minimise disruption.
