any sanitaryware suppliers or fitted bathroom furniture people out there?

i'm looking for units (probably shaker style in light oak/grey oak or possibly more modern and simpler style in metallic grey) to house concealed cistern, btw pan and undermounted basin with either stone or stone effect worktop.

could build something myself from timber and buy the doors from a local kitchen supplier and worktop from a local stone supplier but wondered if anyone out there has recent experience with any companies who could supply this type of thing

i'm in essex by the way
