Of course we offer a guarantee on our showers and installation and are pleased to offer a 25 year written warranty. Your REAL guarantee, however, is the research, development, testing and retesting that every component has jointly and separately undergone. The cost of failure is such that it is only common sense to specifically target the best fit-for-purpose products and product partners. Showers and Wetrooms are only limited by your imagination so there are always things we are adding or improving on, but the fundamentals will never be compromised. Apart from the overall compliance and acceptance testing already published here, if there is something specific you are unsure of, please contact us.
