Which bathroom renovation suits you?
From a refresh to a completely new bathroom: for each, what happens and what to look out for.
Completely new bathroom
Everything out down to the bare floor and walls: new pipes, drainage, waterproofing, tiles and sanitaryware. The best choice with old pipes or leaks.
- Pipes and drainage renewed
- Waterproofed from the base up
- Layout completely free
- The longest lifespan
Tiling over existing tiles
New tiles over the old ones, if those are firm, flat and dry. Less demolition and a shorter lead time.
- Less demolition and dust
- Shorter lead time
- Floor becomes slightly higher
- Only on a sound base
Walk-in shower
A shower without a tray or step, with a glass screen and a channel or point drain on a fall. Spacious and easy to clean.
- No step, easy access
- Channel or point drain on a fall
- Made-to-measure glass screen
- Good waterproofing is crucial
Small bathroom
In a small space every centimetre counts: a wall-hung toilet, a slim vanity and a glass screen make the difference.
- Wall-hung toilet with concealed cistern
- Slim or floating vanity
- Glass screen instead of a curtain
- Light tiles and good lighting
Bathroom in the loft
With a dormer or roof extension the bathroom often goes upstairs. Drainage, ventilation and waterproofing are planned from the design stage.
- Drain with fall to the soil stack
- Shower where there is most height
- Ventilation and extraction
- Floor strong enough for tiles
New toilet
A new wall-hung toilet, basin and tiles, as a separate job or together with the bathroom.
- Wall-hung toilet with concealed cistern
- New tiles and lighting
- Made-to-measure hand basin
- Often done in a few days
Bathrooms in every type of home
Every home sets its own demands for pipes, floor and waterproofing. This is what we see most in the Randstad.
Pre-war buildings with timber floors
Timber joists need a stiff, waterproof base before tiling. Otherwise tiles and grout crack.
1930s homes
Often a small bathroom upstairs with old pipes. A completely new bathroom with new pipes is usually the best choice here.
Post-war homes and walk-up flats
Concrete floors and standard sizes. Tiling over tiles is more often possible here, if the pipes are in good order.
Apartments
Waterproofing and noise matter even more, because a leak affects the neighbours. Check the VvE house rules.
Where a bathroom renovation goes wrong
A bathroom always looks good at handover. The mistakes show later. This is what we see most, and how we prevent it.
No or an interrupted waterproofing layer in the shower.
We apply continuous waterproofing, with sealing tape in the corners and around penetrations.
Too little fall, so water stays on the floor.
We lay the floor to fall towards the drain and check it before tiling.
Old pipes left in place that will soon leak.
We assess the pipes and replace them where needed, before tiling.
Too little ventilation, leading to mould.
We fit extraction with enough capacity and make sure fresh air can come in.
Tiling on a timber floor that flexes.
We stiffen the base first, so tiles and grout don't crack.

How to make a bathroom truly watertight
A beautiful bathroom is one thing; a bathroom that is still leak-free after ten years is real craftsmanship. The difference lies beneath the tiles.
A watertight build-up beneath the tiles
Before we tile, we apply a liquid seal to the wet areas, with sealing tape in the corners and around the shower drain. Sealant alone is not waterproofing. This invisible layer decides whether your bathroom is still dry in ten years' time.
Fall, pipework and ventilation
The shower floor is given the correct fall towards the drain, otherwise water stays put. We replace old pipework straight away, because getting to it later means breaking things open again. Good mechanical ventilation or a heat-recovery unit removes moisture and prevents mould, especially in a room without a window.
Choosing tiles and sanitaryware
Large tiles look calm, but call for a flat substrate; small tiles and mosaic give more grip. A walk-in shower is stunning, but places higher demands on fall and sealing. We think along with you about what suits your space and how you use it.
Common mistakes
- No fall, or too little, towards the shower drain, leaving water standing.
- Relying on sealant instead of a membrane, resulting in leaks to the floor below.
- Underestimating the ventilation, so mould appears in the grout within a year.
Tackling more at the same time? Combine it with a full home renovation or a new kitchen while the pipework is open anyway.
