Sharpened Ideas
Walls Improve Layout Design Fittings
Ceramic tile in wet & wall paper indry area
See pictureInstall an additional grab bar toshower area
Glue wall tile directly to concrete Shorter ceilings (2.7m to 2.5m) Emergency call button
Delete window sill Door/partition Shower head with massage function
Ceiling Screen instead of door Foldable chair in shower
Scrap finish Change (1) partition wall tointegrate furniture
Install UV light
False ceiling to decrease wall finishChange door/wall to moveabletransparent partition
Install moveable clothes drying racks
Perforated false ceiling Enlarge door area Emergency lighting
Floor P & D Shelf by basin
Imitative granite tileTransparent pipes; use sharedpipes
Change fittings, WC, basin and mixerto better quality and reasonable costto total less than $3000 per unit
Delete skirting/cove tileUse plastic pipe (PVC) (Class B)
Install basin cabinetHygienic P&D design
