A niche is not just a hole in the wall
A recessed shower niche is a practical way to store bottles without adding a shelf to the room. A bench can make a shower more comfortable and accessible. Both features also create extra corners, joints and changes of plane inside one of the wettest parts of the bathroom.
They need to be designed into the waterproofing detail from the start.
The waterproofing must follow the shape
The back, sides, top and bottom of a niche all form part of the wet-area surface. The corners and junctions need the appropriate preparation, reinforcement and membrane treatment for the selected system. A tile adhesive and grout are not a substitute for waterproofing beneath the finish.
The same applies to a bench. Its top must shed water appropriately, its edges need to be resolved, and the support beneath it must be suitable for the construction and loads involved.
Penetrations need special care
Mixer outlets, shower arms and other fittings pass through the waterproofed wall. The waterproofing system and the fitting detail need to be compatible. Simply applying extra silicone around a penetration is not the same as incorporating it into the wet-area system.
The manufacturer’s system instructions should control primers, coats, reinforcement, curing and compatible sealants. Mixing unrelated products can create uncertainty around performance and warranty.
Finish the detail before choosing the trim
The niche size, tile layout, shelf thickness, lighting and bottle height should be considered together. A beautiful niche with awkward tile cuts or no useful fall is not a successful detail.
In a Durban bathroom, the room’s humidity makes good ventilation important, but ventilation does not repair a waterproofing weakness. The water must be managed at the construction layer first.
