Waterproofing and drainage
A waterproof membrane under the tiles, a fall towards the floor gully, and connections tested before anything is closed up: that is what stops a badly finished shower from staining the ceiling of the flat below.
The work sequence is set during the visit, before the quote is written, so materials and trades arrive in the order your home's layout actually demands.

Refine with 3 photosIndicative Belgian market ranges for 2026 — this is not our price list. Your exact price is confirmed in writing after the free site visit, and it doesn't change after that. The 6% rate applies to homes occupied for more than 10 years, used mainly as a private residence, with materials invoiced by the contractor.
One point of contact, one schedule, one invoice. We do not let waterproofing, tiling and electrics be handled by three crews that never talk to each other.
Waste removal dictates the order in which work can proceed, and that order is locked in during the site visit before any quote is written. A bathroom stripped to its frame produces considerable debris, and when that debris must leave through a house in occupation, the sequence of trades – what comes first, what follows, where each team has access – becomes as important as the work itself. This discipline is how a house stays functional while its bathroom is rebuilt.
A waterproof membrane under the tiles, a fall towards the floor gully, and connections tested before anything is closed up: that is what stops a badly finished shower from staining the ceiling of the flat below.
A curbless walk-in shower needs a fall and a drain that fit within the depth of the floor. We check the existing screed at the survey, and tell you plainly if the slab means a small upstand rather than a perfectly flat floor.
A bathroom without mechanical extraction stays damp long after the shower is off, and mould returns on new tiling as readily as on old. We fit an extractor sized to the room, ducted to an existing outlet or a new one built for the job.
Sockets, lighting and electric heating follow the safety zones around the shower and the bath, set out in Belgium’s AREI/RGIE electrical code — not a standard socket fitted within splash range because it was easier.
Moving the soil stack changes where the shower or toilet can sit, but stays impossible when it serves several flats through a shared duct or runs through a load-bearing slab. We check this before drawing a layout that cannot actually be built.
Shower, bath, toilet, vanity unit and taps fitted and connected, finishing joints included. Cleaning the site is part of handover, not a line added on afterwards.
The price is fixed at step 3. After that, it does not move without your signature.
A call, or a few photos of the current bathroom over WhatsApp. We tell you straight away whether your project fits what we do — and if it does not, we say that too.

The ranges the market charges in 2026, published as they stand. Your quote may fall below or above them — it will be calculated, not estimated.
Indicative Belgian market ranges for 2026 — not an Alpha Services price list. Amounts excl. VAT. Fixed quote confirmed before work begins.
Five provinces under one planning code (the CoDT) — but grants and deadlines that run on their own calendar, not Brussels' or Flanders'.
If changes emerge during work – fixtures the homeowner wants adjusted, or structural surprises the opening of a wall reveals – a written addendum is prepared, costed and approved before that work begins. This keeps the fixed quote accurate and the homeowner's decision visible to the whole team.
The 5 provinces we cover
The municipal council (collège communal) issues most permits, with an official timeline of 30 to 115 days depending on the procedure. Since 1 May 2025, a wider list of work is exempt: openings in a flat roof, bike shelters, covered parking for active mobility up to 60 m², HoReCa terraces up to 100 m², solar panels, heat pumps. Watch out for ground-mounted solar panels: the unlimited-surface exemption only applies in an economic activity zone — in a residential zone, a permit is still required.
Against a refusal, the applicant, the municipal council or the regional planning delegate have 30 days to appeal to the Walloon government. A third party — a neighbour, say — has no access to that administrative route and must go straight to the Council of State, within the standard 60-day period.
As of 24.07.2026, Prime Habitation is still accepting applications, final invoice included, up to and including 30 September 2026 — check energie.wallonie.be before any quote that would run past that date. An energy audit by a certified auditor is mandatory before work starts, except for roofing. Separately, the SWCS's Rénopack finances €1,000 to €60,000 at 0% interest, for a project capped at €62,500, repayable before the borrower's 86th birthday.
Nothing applies today: from 2028, anyone buying a home labelled E, F or G will have to reach at least label D within 5 years of the purchase deed, then C by 2031, B by 2036, A by 2041. Unlike Brussels, this obligation will be triggered by the purchase itself, not by a single calendar for every owner. We don't apply it to a project signed in 2026 — but we do factor it into a quote for a home that's about to change hands.
