Recent Plumbing Projects

For the prestigious Park Lane Hilton Hotel in London we have installed new male and female toilet and shower facilities. The challenge on this particular project was gaining direct access to the main drains as the toilet block was in a basement. To overcome the problem we traced out the drainage system servicing the hotel complex and worked out a way of getting the drainage from the toilet blocks into the main sewers using a gravity feed system without the need or complication of an expensive pump system.

On a smaller scale, but of no less importance for the customer, is a bathroom refurbishment in Brentwood that we have recently completed. There were several challenges to this project, including the installation of an oversized bath into a marble recess without it overpowering the rest of the bathroom. By incorporating a bigger basin, creating more space around the toilet area and adding a range of products and different themes, the result is an elegant bathroom that is attractive, safe and practical for a growing family.


In a large house in Hutton, Brentwood, we have replaced the heating system and introduced 12 cast iron radiators, to complement the Victorian themed design of the house

In a home in Billericay we have installed a bathroom suite with all the trimmings, including a top of the range Cross-Water shower, with level access tray – meaning no trip edges. The transformation was completed with a full height towel rail, oak floor and decorative, bespoke wall radiator.
