Bathroom renovation is one of the most commonly requested jobs, and one of the hardest to coordinate — plumbing, electrical work and tiling all meet in one small room. Below is the step-by-step process and indicative prices by bathroom size.

Price by bathroom size

Small bathroom (3–5 m²) – approximately 98 700 CZK.

Medium bathroom (5–8 m²) – approximately 126 200 CZK.

Large bathroom (8+ m²) – approximately 161 100 CZK.

Prices include tiling, sanitary ware, a shower enclosure, and plumbing and electrical labour. Underfloor heating is an optional add-on at 19 000 CZK extra.

The bathroom renovation process

1. Removal — taking out the old sanitary ware, tiling, and debris disposal.

2. Waterproofing — new waterproofing across the whole wet area, essential against future leaks.

3. Plumbing and drainage — new water and waste lines laid out for the new fixture positions.

4. Electrical work — lighting, sockets, and prep for a washing machine or dryer if needed.

5. Tiling — to your chosen material quality.

6. Sanitary ware and fittings — toilet, sink, shower enclosure or bathtub, mirror, and an optional heated towel rail.
