When it comes to apartment renovation, a bathroom renovation is the most expensive, technically complex, and high-risk zone. Even a minor mistake made here can turn into a leaking ceiling for your neighbors or moldy walls within a few months.

The team at the construction and renovation company RENART has gathered the main mistakes most commonly made during independent projects, which can drastically impact your final renovation estimate.

"Tiles are waterproof" — this is the biggest myth. Water and moisture still penetrate through the grout joints between tiles. If high-quality bathroom waterproofing is not applied under the tiles (especially in the shower area and on the floor), the walls will absorb moisture. According to RENART standards, applying multiple layers of liquid waterproofing is the most crucial stage.

2. Hidden Plumbing Pipes Without an Access Panel

Hiding plumbing pipes and manifolds inside the walls looks aesthetically beautiful, but it is critically important to maintain access to filters and shut-off valves. If you don't include a hidden revision access panel (which gets covered with tiles and remains completely invisible), you will have to demolish the entire wall in case of any minor leak.

3. Ignoring the Ventilation System

A small window is not enough for proper bathroom ventilation. Poor ventilation results in black mold in the corners, constantly fogged mirrors, and unpleasant odors. When we start a comprehensive apartment renovation in Tbilisi, we always calculate the cubic volume of the space to select an extractor fan with the appropriate power.

4. "Ceiling-Only" Lighting

Leaving only one central light fixture in the bathroom is a mistake. Light coming strictly from the ceiling casts shadows on your face, making it inconvenient when looking in the mirror (for makeup or shaving). Zonal lighting is required — for example, LED lighting around the mirror.

5. Incorrect Tile Calculation and Planning

People often buy tiles based on exact square footage without accounting for cuts and waste. As a result, they run short of a few tiles at the end, and the exact color match is no longer available in stores. A turnkey renovation is beneficial precisely because engineers fully control material calculations and logistics from start to finish.
