Hi I would like to know how I can might reduce the sound levels of the air blower used with a spa bath (also the water pump used for the Whirlpool) I have fixed the air-blower directly onto the floorboards at present and wondered if I should mount this on thick rubber instead for sound damping and to reduce vibration? Would this help at all? Also would it be beneficial to partly enclose the motor within something with sound proofing properties (allowing for air movement of course) The bath has not been boxed in fully yet. Any other ideas would be appreciated thank you Adrian

We have a 2 year old house (slab floor) and have noticed in the walk-in shower stall, the grout has a long separation between the 1x1 floor tiles and the 4x4 wall tiles. I can't call it cracked, it just looks like the edge of the grout separated from the edge of the wall tiles. I am concerned with water getting under the floor even though I know there is a liner under there. Should we do this repair by re-grouting which would be a new repair experience for us, or would caulk do? If caulk, what kind of caulk would stick? Thanks! Legacy
