Bathroom Fitting in Erith — Supply, Install & Finish
Full bathroom installations, wet rooms, en-suites and disability adaptations across Erith, Belvedere, Thamesmead and surrounding areas. Free consultation, written quote, no obligation.
Bathroom Renovation Done Right
A bathroom renovation is one of the most significant improvements you can make to a home — and one of the most complex, involving plumbing, tiling, waterproofing, electrical work and carpentry all in one space. Thames Plumber Services manages the plumbing and installation side of bathroom fitting across Erith, Belvedere, Thamesmead, Slade Green, Abbey Wood, Crayford, Northfleet and Swanscombe.
We're qualified plumbers with genuine bathroom installation experience — not general builders who occasionally do bathrooms. Every bathroom project is handled by engineers who understand the critical details: correct waste gradients, waterproofing behind tiling, correct shower tray installation, ventilation requirements.
Getting these details wrong causes expensive long-term problems. Getting them right means a bathroom that looks great and functions properly for fifteen or twenty years.
Bathroom Fitting Services
From complete bathroom renovations to targeted upgrades — we cover the full range of bathroom plumbing and installation work.
Full Bathroom Suite Installation
From £1,200 (labour)A complete bathroom replacement — new bath, basin, toilet and shower facilities — typically takes three to five days. We handle the full plumbing scope: removing existing suite, capping, rerouting and installing all new supply and waste pipes, fitting the new suite, and connecting all wastes correctly before tiling begins.
We work with bathroom suites you supply, or we can source quality suites through our trade accounts at competitive prices. We'll advise on quality levels — the market varies significantly from budget suites to quality units that hold up after ten years of daily use.
Wet Rooms
+£500–£800 vs standard showerA wet room requires specialist waterproofing that goes significantly beyond standard bathroom installation. The tanking membrane must cover the full floor and walls to sufficient height, be applied correctly, and be fully compatible with the adhesives and tiles used.
We install wet room systems properly: correct selection of a suitable former or screed to achieve the required fall to the drain, correct application of liquid tanking membrane or sheet membrane system, and careful coordination with tiling to ensure no water penetration.
En-Suite Installation
Quote on requestEn-suites in older homes often require creative pipework solutions to reach existing waste stacks or create new waste runs. We assess feasibility at the design stage so there are no surprises during installation.
We fit en-suite shower rooms of all sizes, from compact 900mm x 900mm enclosures to more generous double-width walk-in showers. We'll advise on the right shower type (mixer, electric, digital) based on your water pressure and existing boiler setup.
Walk-In Shower Conversion
From £800 (labour)Converting a bath into a walk-in shower is one of the most popular bathroom projects we carry out, and one that adds significant practical value for homeowners of all ages.
The existing bath waste can often be adapted for the shower tray waste, simplifying the plumbing. We advise on shower tray options — acrylic, stone resin, level-access — based on your preferences and the floor structure.
Disability Bathroom Adaptations
DFG grants availableWe carry out bathroom adaptations for elderly or disabled residents — level-access wet rooms, walk-in shower conversions, grab rails, thermostatic shower valves and raised toilet installations.
These adaptations can be funded in part through Disabled Facilities Grants (DFGs) administered by local councils. We provide written quotes in the format required for grant applications. Call 01474 329154 to discuss.
Bath Replacement
From £400 (labour)Replacing just the bath — swapping an old cast iron or fibreglass bath for a new acrylic model, or installing a freestanding bath — is a more straightforward project but still requires correct waste installation.
Often requires some tiling remediation around the new bath edge. We handle this correctly, ensuring watertight installation that won't cause long-term water ingress.

The Bathroom Fitting Process
From initial consultation to final handover — here is exactly what happens on a Thames Plumber Services bathroom project.
Free Consultation
We visit the property, assess the existing bathroom layout, discuss your requirements and preferences, review any constraints (pipework locations, water pressure for shower type selection) and take measurements. No charge, no obligation.
Written Quote
We provide a detailed written quote covering all plumbing work involved. If you're supplying the suite yourself, we'll advise on specifications we need before confirming the final price.
Installation
We protect adjacent areas, strip out the existing bathroom carefully (water isolated, electrics isolated), and begin the new installation. We work through the plumbing first, before tiling begins, to ensure all connections are correct and tested.
Testing & Sign-Off
All supply connections are pressure-tested, all waste connections are run-tested, the shower is operated at full flow to check the waste gradient performs correctly. Any adjustments are made before we leave.
Handover
We walk through the completed work, explain any maintenance requirements (silicone sealant refresh timing, shower valve cartridge care) and hand over the 12-month workmanship guarantee.

Frequently Asked Questions
How much does a full bathroom installation cost?+
Labour costs for a full bathroom installation (removing existing suite, all plumbing, fitting new suite, excluding tiling and supply of the suite itself) typically range from £1,200 to £2,000 for an average-sized bathroom. Supply of a quality mid-range bathroom suite adds £500–£1,500. Full project costs including tiling typically run from £3,000 to £6,000+. We provide a written, itemised quote so you can see exactly where the cost sits.
How long does a bathroom installation take?+
A full bathroom renovation — strip out, replumb, new suite, then tiling — typically takes five to eight working days depending on the project scope. A straightforward like-for-like suite replacement with minimal tiling work can be completed in two to three days.
Do you tile bathrooms as well?+
We don't carry out tiling ourselves. We can recommend reliable, experienced local tilers who work alongside our projects regularly, or you can arrange your own tiler. We coordinate with the tiler to ensure the sequence of work is correct — our plumbing work is always complete and tested before tiling starts.
Can you fit a bathroom in a property with low water pressure?+
Yes, but the shower type selection is critical. Mixer showers require adequate mains pressure to work well. In lower-pressure situations, a pressurised shower pump or an electric shower (which heats its own water and doesn't require high pressure) may be the better choice. We'll assess your water pressure at the consultation stage and advise accordingly.
Are you able to carry out bathroom adaptations for elderly or disabled users?+
Yes. We install level-access wet rooms, low-threshold shower trays, thermostatic valves and grab rails for accessibility. For works funded by a Disabled Facilities Grant, we provide quotes in the format required for the application. Call us to discuss your requirements.
