Tile Niches and Boxing in Warsaw — Build and Finish

A wall niche behind the bath for shampoos and gels — no more suction-cup shelves that fall off. Boxing around risers so pipes are hidden. These are the features that make a bathroom functional and neat. Building a niche or boxing means a frame of Knauf profiles, moisture-resistant plasterboard, waterproofing, and tile installation precisely aligned to the main wall. We build niches and boxing across Warsaw — from Targowek to Wlochy.

How much does it cost and what affects the price

The cost depends on the structure size, shape complexity, number of niches and chosen tile. A simple 30×40 niche covers framing, plasterboard, waterproofing and tiling. Boxing around risers depends on height and number of access panels. Materials are charged separately. Current prices are in the table below.

How the work is done on site

1. Measurement and planning. We determine the niche or boxing size, align it to the tile layout (so niche joints match the main wall) and position access panels for valves and meters.
2. Frame assembly from Knauf CW/UW profiles — rigid, double-fixed at corners.
3. Plasterboard cladding. Moisture-resistant board (green GKBI) is essential for bathrooms. Double layer on external corners for rigidity.
4. Waterproofing. All niche and boxing surfaces in the wet zone are treated with liquid membrane (Mapei Mapelastic, Ceresit CR 166).
5. Tiling. We start from the main wall then move to the niche/boxing so joints align. External corners get an aluminium trim or a 45-degree mitre.
6. Grouting and sealing. Epoxy grout in wet zones. Niche-to-wall junctions sealed with colour-matched sanitary silicone.

Common mistakes with niches and boxing

• Niche not aligned to the tile layout — joints do not match the wall, looks unprofessional.
• Standard plasterboard instead of moisture-resistant — it swells and crumbles in a bathroom.
• No waterproofing inside the niche — water accumulates behind tiles, mould grows, board fails.
• Weak frame — the niche flexes when pressed, tiles crack at joints.
• No access panel in boxing — no way to reach valves, meters or traps. In an emergency the whole boxing must be demolished.
• Unprotected external corners — without a trim or mitre, tile edges chip on impact.
• Niche too shallow — bottles do not fit. Minimum 10-12 cm depth.

What to prepare before the technician arrives

• Decide on niche sizes, positions and heights.
• LED lighting in the niche? Cables must be run before cladding.
• For boxing — determine access panel positions (valves, meters, traps).
• Knauf CW/UW profiles.
• Moisture-resistant plasterboard (green GKBI).
• Waterproofing membrane.
• Tiles — with extra for niche cuts.
• Aluminium corner trims (or the technician will mitre).
• Access panels of the correct size.
• Clear the work area.

A real case from Warsaw

A bathroom in Targowek, 6 m² — the client wanted two niches behind the bath and boxing around a vertical riser with an access panel. We laid out 60×30 tiles on the full wall first, sizing each niche to exactly one tile width so joints aligned. Frame from Knauf CW 50, double-layer GKBI on corners. Waterproofed inside the niches and on the boxing with Mapei Mapelastic. Tiles on Ceresit CM 17, external corners mitred at 45 degrees (client preferred no aluminium trim). Hidden access panel 20×30 cm flush with the tile surface. Grouted with Mapei Kerapoxy. Three days of work. The niches fit seamlessly — joints line up with the main wall as if they were always there.

Frequently asked questions

Who does the work

Niches and boxing are built by technicians skilled in both plasterboard work and tiling — a combined discipline. We arrive with profiles, board-cutting tools, a laser level and a full tiling kit. We cover all of Warsaw. Call or message — we will discuss the design and quote a price.
