Sanislim WC Macerator Unit (Slimline) Saniflo macerator pumping systems enable you to add facilities almost anywhere. All you need is a water and electric power supply. They're easy, quick and economic to install and you can add a new toilet under the stairs or in a garage, basement or loft conversion, a cloakroom, shower room or bathroom - even a complete kitchen or utility room with dishwasher and washing machine. Add a washroom, shower unit or even a complete en suite shower room based on SLIMLINE SANITARYWARE. Ideal for use in a basement or loft extension - or in any home improvement where conventional large bore pipework is impractical.
