Bathroom Renovation Services in Hertfordshire
Full design, supply and installation. CAD design included. Bathroom Renovations from £6,500 (or as appropriate)
A bathroom that works properly for the next fifteen years is decided long before the first tile goes on the wall. It’s the layout drawings, pipework routing, waterproofing detail, extractor sizing and trade coordination that separate a renovation you keep enjoying from one that starts causing problems in year three.
Our Bathroom Renovation Process & Services
Planning Your Renovation
Design starts with a room measurement and a services check – not a picture book. We take accurate measurements, note the soil-stack position, check water pressure, inspect visible pipework, and confirm the electrical layout. Only then does the design work begin.
Every renovation over £12,000 includes free 3D CAD design. You see the finished room – layout, tile choice, brassware, storage – before committing to anything. Small adjustments at the drawing stage cost nothing; the same change once tiling has started can be a full day of rework.
Bespoke Luxury Bathrooms
For premium projects, we work with Villeroy & Boch, Duravit, Hansgrohe, Crosswater and other high-end brands. Bespoke shower enclosures, freestanding baths, natural stone tiling, underfloor heating, mood lighting, and fitted furniture all feature regularly. What makes a luxury bathroom last isn’t just the specification – it’s the detail behind the finishes: concealed cisterns need proper service access, wall-hung vanities need genuine wall strength, and large-format porcelain needs a perfectly flat substrate. These are the details we design around from the start, not problems to fix later.
Complete Bathroom Renovations
A complete renovation is a proper strip-out and rebuild. Everything comes out – old suite, tiles, subfloor coverings, decayed pipework, boxing that’s outlived its purpose. What goes back in is designed for the current household, not the one that lived in the property decades ago.
A typical family bathroom refurbishment runs 7-12 working days on site. Larger master bathrooms or full strip-out rebuilds run 10-14 days. Wet-room renovations with proper drainage falls and tanking sit around 10-14 days. We handle disposal, protection of surrounding rooms and building fabric, and the day-to-day project coordination so you’re not chasing three trades yourself.
Bathroom Plumbing
A renovation is the one point where years of retrofitted plumbing finally get sorted properly, rather than tiled over again. Behind most Hertfordshire renovations we find a mix of ageing copper, occasional lead, cast iron drainage, and pipework that’s been extended and rerouted by different tradespeople over the years – compression fittings weeping quietly behind kitchen units, waste runs with insufficient fall, pinhole corrosion at solder joints. Because a renovation is a full strip-out, it’s the one chance to replace what’s failing properly instead of working around it again, which is why we treat existing pipework as part of the renovation scope, not a separate job. Our wider plumbing services cover diagnosis and repair on anything the strip-out reveals.
Ventilation & Extractor Fans
Ventilation is the detail that quietly ruins renovated bathrooms when it’s done wrong. An undersized extractor, a duct route that discharges into a loft void, or a fan positioned across the room from the shower will all leave humidity in the air long after you’ve finished bathing – and that humidity ruins grout, warps furniture, peels paint and encourages mould behind sealants. We fit humidity-sensing extractors sized for the room volume, ducted to the external wall on the shortest sensible route, with overrun timers and back-draught shutters. Windowless bathrooms get particular attention – a proper mechanical solution rather than a token fan.
See Your New Bathroom Before We Lift a Single Tile
We use CAD software to produce a detailed 3D design of your new bathroom before any work begins. You’ll see exactly how your chosen layout, fixtures and finishes will look and we won’t start until you’re completely happy.
Fully Tanked. Fully Waterproofed. Guaranteed.
Every Vantage bathroom is fully tanked and waterproofed before a single tile goes up. This is the foundation of a bathroom that lasts and something many cheaper installers skip. We don’t.
All bathroom installations come with a 2-year labour guarantee. If anything we’ve fitted has a problem, we’ll come back and sort it. No quibble.
Our Recent Projects
Common Problems We Solve
The recurring issues we find once the old bathroom comes out:
- Damp that's tracked through to the ceiling below - years of untanked shower walls letting water reach the joists above
- Silicone that's failed repeatedly - the previous bathroom went in without proper tanking behind the tiles
- A concealed cistern or valve with no way to reach it - sealed in behind tiles by whoever fitted the last bathroom
- Waste pipes that were never laid to the right fall - basins and baths that have drained slowly for years
- A heating system that's never been rebalanced since the original install - cold radiators or towel rails nobody's addressed
- Decades of retrofitted pipework running in directions that make no sense for the room as it exists today

Frequently Asked Questions
How much does a bathroom renovation cost in Hertfordshire?
It depends on the size of the room, the specification and whether the layout is changing – so we don’t quote a figure without seeing the property. A free on-site survey gives you an itemised quotation with an accurate cost, not a generic estimate.
How long does a full bathroom renovation take?
A standard family bathroom refurbishment runs 7-12 working days on site. A full strip-out and rebuild takes 10-14 days. Wet rooms 10-14 days including proper tanking. Premium master bathrooms with bespoke fittings can run 12-18 days. A realistic quotation includes contingency for anything discovered during strip-out.
How do you manage plumbing, tiling and electrical work during a renovation?
Across a full strip-out and rebuild, one project lead coordinates the plumbing, tiling and Part P qualified electrical work stage by stage, so the programme runs to schedule with a single point of accountability from first fix through to handover – not several separate contractors you have to chase individually.
Is waterproofing behind the tiles really necessary?
Yes, in shower enclosures, wet rooms and bath-shower combinations. Tiles and grout aren’t a waterproofing system – grout is porous and silicone eventually fails. A proper two-coat liquid membrane behind the tiles prevents water reaching the substrate and timber subfloors. It’s the single most cost-effective spend in any renovation.
Do you offer 3D design before I commit?
Yes – 3D CAD design is included free on renovations over £12,000. You see the finished layout, tile choice, brassware and storage before signing off the specification. Adjustments at the drawing stage cost nothing; changes once tiling has started can add days of rework and material costs.
Do you work in older properties with dated plumbing?
Regularly – most of the Victorian, Edwardian and inter-war housing across Hitchin, St Albans, Berkhamsted and surrounding areas has ageing pipework that needs assessment during any renovation. Where existing plumbing should be replaced, we handle it as part of the project rather than tiling over a future problem.
