Bathrooms
Small room. Big upgrade.
From quick facelifts to full refits, we design and build bathrooms that feel bigger, work better, and last longer. Smart layouts, quality brassware, proper waterproofing, and quiet ventilation solve the common issues—damp, weak showers, no storage. We handle everything: design, materials, electrics, plumbing, tiling, and certification.
