Bathroom renovation in Woluwe-Saint-Lambert

Technical points for a successful bathroom renovation

Waterproofing: the foundation of a durable bathroom

A poorly waterproofed bathroom is one that leaks, sometimes without any visible signs, for years, until damage appears on the ceiling of the lower apartment or in the shared wall. In bathrooms from the 70s-80s, built-in shower trays or bathtubs placed directly on masonry often lead to leaks. We systematically apply a liquid waterproofing system under tiles (Schlüter, Wedi or equivalent) on all wet surfaces before laying the covering.

Plumbing and drainage: often needs to be redone in older installations

Lead or cast iron pipes from installations before 1980 are nearing the end of their lifespan. In a bathroom that is to be completely renovated, it is often more economical to redo all the drainage and supply lines rather than patching around the existing ones. We carry out this work according to the rules of the trade, using materials that comply with current standards (PER, copper, soundproof PVC). In a condominium apartment, we check the pathways for ducts and common columns beforehand.

Ventilation: essential to avoid mold

A bathroom without proper ventilation produces condensation. Over time, mold appears on the joints, then on the partitions, and then in the structure. In older Woluwe homes, passive extraction vents are often insufficient. Installing a humidity-controlled mechanical ventilation system type B (which adjusts extraction to the humidity level in the room) is the most effective and economical solution. It can often be connected to the existing duct without major work.

Bathroom heating: options and comfort

An electric towel warmer with inertia or hydroelectric heating is a great replacement for the old water radiator in a renovated bathroom. It allows for heating the room independently of central heating, which is practical in mid-season or for a quick warm-up in the morning. For new high-end bathrooms, electric underfloor heating under tiles is a highly sought-after solution in high-end Woluwe apartments: optimal comfort, absence of bulky heating bodies, and discreet integration.

Duration of work and practical organization

A complete bathroom renovation typically lasts 10 to 15 working days. During this period, access to sanitary facilities is limited. We plan the project taking your constraints into account: if a second toilet or a replacement shower is available in the apartment, occupancy can be maintained. For apartments without alternatives, we prioritize working on networks and heavy finishes first, in order to quickly restore the sanitary facilities to service.
