Bathroom renovations may seem simple, but they involve plumbing, electricity, tilework, and waterproofing — all in one of the smallest spaces in the house. One mistake can cause years of problems. In humid, coastal towns like Çeşme, bathroom renovation must be handled with extra care. At Küresel İnşaat, we avoid these 5 critical errors. ❌ Top 5 Mistakes in Bathroom Renovation: Not Replacing Old Pipes If old pipes under the floor are not replaced, leaks are only a matter of time. Poor Waterproofing Tiles are not enough. Apply liquid waterproof membranes, especially around shower areas. No Floor Slope to Drain Flat bathroom floors cause water to pool and seep through grout joints. Wrong Tile and Grout Selection Glossy tiles are slippery. Bad grout absorbs water and gets black over time. Ignoring Electrical Safety Wet zones need IP-rated sockets, switches and LED lighting to prevent short circuits. ✅ What to Do: Always replace old installations Apply proper waterproofing under tiles Create slope to drains Use moisture-safe electrical fittings Work with a professional team At Küresel İnşaat, we follow these principles in every bathroom we renovate in Çeşme and Alaçatı.
