A shared bathroom refit replaces worn or failing bathrooms in an HMO with hard-wearing, easy-clean ones: good extraction, waterproofing, thermostatic showers and finishes that stand up to several users a day. For a house in Horsham we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately.
