Client Voices

What our clients tell us.

★ ★ ★ ★ ★
Martina and the team transformed our master bathroom into a true sanctuary. The level of design thought — from the brassware specification down to the millimetre-accurate installation drawings — was beyond what we'd experienced from any other studio.
Private Client
Master Bathroom · Oxford
★ ★ ★ ★ ★
We approached InStil for a contract specification on a residential development and they delivered comprehensive 3D designs and detailed drawings that made the installation phase remarkably smooth. A first-class trade partner.
Architect Practice

Visiting the Garsington showroom changed our project entirely. Seeing eight fully installed bathrooms in person — being able to feel the brassware, walk into the wet rooms — gave us confidence the catalogue route simply couldn't.

Award-winning is one thing — but what InStil delivers in practice is calm, considered, end-to-end project management. Three bathrooms designed, supplied and installed without a single hitch.
