Our expert team ensures transparency with a free on‑site assessment, written fixed pricing, and workmanship warranty.
1. Initial Assessment for a Bathroom Project in Ataşehir
During the free on‑site assessment, we inspect the bathroom’s structural condition, plumbing, and electrical layout. New constructions in Ataşehir typically feature reinforced‑concrete frames and prefabricated wall panels, which influence demolition scope and waterproofing strategy.
- •Check load‑bearing walls according to building type (concrete vs. prefabricated)
- •Assess age and code compliance of existing plumbing
- •Obtain water and waste discharge permits from Istanbul Metropolitan Municipality
2. Design and Material Selection
Ataşehir’s humid climate makes slip‑resistant ceramic and waterproof wall cladding essential. Large‑format porcelain tiles, popular in contemporary projects, offer both aesthetic appeal and easy maintenance.
- •Slip‑resistant tiles (R10‑R13 rating)
- •Waterproofing membrane compliant with EN 1504‑2
- •Aluminium or stainless‑steel shower profiles (corrosion resistant)
3. Permits and Regulations
In Istanbul, bathroom renovations must comply with the Zoning Law No. 5399 and the Electrical Installation Regulation No. 6331. For condominiums, a renovation permit from the board is mandatory, and water service to common areas must remain uninterrupted.
- •Building‑specific renovation permit (Istanbul Metropolitan Municipality)
- •Condominium board approval
- •Technical report for plumbing and electrical works
4. Execution Phases and Timeline
Typically finished within 3‑4 weeks; phases: demolition → waterproofing → wall/floor tiling → plumbing/electrical installation → fixtures and accessories placement. Due to heavy traffic and delivery restrictions in Ataşehir, material deliveries should be scheduled on weekdays between 09:00‑12:00.
- •Week 1: Demolition and infrastructure inspection
- •Week 2: Waterproofing and wall/floor preparation
- •Week 3: Plumbing, lighting, and fixture installation
- •Week 4: Final cleaning, inspection, and handover
5. Budget Allocation and Cost Control
Roughly 40% of the budget goes to tiles and waterproofing, 25% to fixtures and shower systems, 20% to plumbing and electrical work, and 15% to labor and administration. The written fixed price after the free assessment clarifies these ratios for each project.
- •Tiles & waterproofing: ~40%
- •Fixtures & shower equipment: ~25%
- •Plumbing & electrical: ~20%
- •Labor & administration: ~15%
