Does a bathroom in a hotel or serviced apartment in Unaizah really need waterproofing, and what will it cost? The centre of Unaizah sits about 667 m above sea level, and property owners here ask this question because wet floors, tile edges and shower walls take daily use in busy rooms. Bathroom waterproofing is priced in our listings at SAR 15–40 per m², so the cost depends on the area treated and the materials chosen. Spray foam sits at SAR 20–45 per m², epoxy coating at SAR 35–85 per m², and a bitumen membrane at SAR 15–35 per m². Each option suits different wet zones, so the choice should follow the bathroom's layout and how heavily it is used.

Before any work starts, an inspection checks the bathroom from floor to wall height. The technician looks for cracks, hollow tiles, old sealant, and signs of moisture on ceilings or in adjoining rooms. Where cracks are found, crack injection is priced at SAR 40–115 per metre, so the length and position of each crack are measured and recorded. The inspector also notes the drainage point, the shower tray and any joints where water could travel. This written record shows which surfaces need coating and which need repair first, so the owner can compare options before agreeing to a scope.

To make the visit efficient, prepare access to every bathroom included in the survey, including rooms that are rarely used. Clear the floor and remove loose items so the inspector can reach skirting and corners. Share any previous repair records, invoices or notes about leaks, and tell the team which rooms have had complaints from guests or neighbouring units. If the property has a water tank or roof area linked to the bathrooms, mention it, since tank coatings and roof work are priced separately. Having this information ready helps the inspection finish in one visit and gives you a clear plan to approve.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
