Record room length, width, and height at multiple points because old walls bow, floors slope, and corners rarely hit perfect ninety degrees. Note door swings, window placement, pipe centers, and electrical boxes. Add tolerances for tile thickness, backer board, thinset, and fixtures to protect precious inches.
Align fixtures along a shared wet wall to save plumbing complexity and preserve storage. Maintain knee clearance at the toilet, swing clearance for doors, and safe approach to the shower. Favor sightlines that land on calm surfaces, mirrors, or windows, helping your micro-bathroom feel larger and thoughtfully arranged.
Check local permitting for plumbing, electrical, and ventilation changes, then build a realistic timeline that respects lead times for compact fixtures and specialty glass. Sequence demolition, rough-ins, waterproofing, tile, and trim to minimize downtime. Include contingency days and budget, because even tight spaces can hide big surprises.
Choose tall, narrow cabinets, stacked shelves, and above-door cubbies to free floor area and maintain clear pathways. Over-the-toilet units, wall ladders, and ceiling-hung rails offer generous capacity while protecting elbows. Keep daily items at eye level, and use labeled baskets to streamline routines, cleaning, and weekend resets.
Recessed medicine cabinets, shower niches, and in-wall toilet tanks reclaim inches without crowding. Frame niches between studs, slope shelves for drainage, and waterproof thoroughly. A mirrored recessed cabinet can hide outlets and chargers, keeping cords contained while reflecting light so the room reads open, elevated, and calm.
