The concave bath caddy simply sits onto your bath rim, raised on small clear bumpons (so it doesn't slip around). It is perfect for drying your face cloth or for holding your soaps and a glass of wine.
The concave caddy comes in 2 sizes:
Large 820mm x 180mm, the section which drops into your bath is 680mm long and 80mm deep. The large size fits most freestanding baths and the large size built-in baths.
Small 740mm x 180mm, the section which drops into your bath is 560mm long and 80mm deep. The small size fits most regular sized built-in baths.
