I built a long cabinet below the screen area and cut out two of the door panels. So I still have closed door cabinets but two have black speaker material stretched and added behind them. I added loudspeaker material (you can get this on Amazon) - it has worked perfectly for 6 years. (Haven;t got photos here)

Thanks! I was also leaning to leaving the short wall alone but wanted some outside advice :) appreciate the opinions!

Thanks Nitin and Ideal Lifestyle. Sorry for the late reply, I don't know why my net is not working properly from the last few days. Ny way, I actually see the foating kitchen cabinet in google image. May be that it not good for our Indian kitchen. I love the drawyer system that offered in modular kitchen cabinet. But at the same time I have no patience to dry the the kitchenware (cookware/dish etc.) after washing. Now we put it on the steel dish rack (commonly visible in Indian kitchen) hanged in our wall after every wash, which no need to first dry and then store. But I want to conceal the dishes, pressure cookers, kadhais in drawyers. In my dream kitchen big kitchenware should be concealed, hanging cookware like saucepan, tawa, frying pan would hang on s hooks in railing and open shelve for the dry goods in glass/tin/ceramic jar.

Hi, Greetings from Home Credence! Oval shaped mirror can be used here as it will also match the pedestal basin or there are many cabinets available in the market with mirror on front surface and storage space for brushes/toothpaste. So, both of your requirements of mirror and cabinet will get fulfil. For soap dispenser, you can keep it at 15" right from the center of angular cock or match the tiles joint whichever is appropriate at 39" height from FFL. You can also add towel rack on the opposite wall of shower. Thanks & Regards, HOME CREDENCE
