Please don't forget you must have really good drains for this extra water load. Have you considered a tankless water heater? Or at least a separate water heater for the master so that the rest if the household still has a hot water supply and pressure balance. That's something to consider also. I've often wondered, I must admit, how all of this is supposed to work with energy saving measures in place.

I agree with divadeva. More lights. If you can add pot lights do it. If they're already there add task lighting and up the wattage on the bulbs on the pot lights (replace with LED and you can make them brighter because the wattage on LED is lower for brighter light). If you have all of that add decorative lighting. If ventilation is an issue find a way to move the air around or add air filtration. Maybe the HVAC is deficient. Maybe you can add a HEPA filter instead of the standard one that comes with the unit. Call an HVAC specialist to see if there is a way to boost air flow in the room.

Hi, I think full wooden tiles will feel like pathetic. Try disparate like combinations of glossy and wood tiles or like 2 walls and floor with wood tiles and other 2 walls light colored glossy tiles to break the monotony.Thank u.
