Thank you for the opportunity to work on your project. It was a real pleasure for me to try and create more comfortable and efficient space for your family.
I am suggesting very open space and in the same time maximizing it as much as possible. I have tried to keep the feel of cosines and comfort.
As you required I am suggesting wide open walk-in shower with a lovely Glass panel and door instead of the bath tub. Enter the wooden floor shower. It's an elegant upgrade to the materials. Because water trickles through the slats into a large shower, a wood floor conceals unsightly drains, making way for a fluid, minimalist statement. With less splash back works perfectly in the space. Contrasting a sleek, contemporary aesthetic with the texture of wood creates a calming vibe. The material also has the uncanny knack of instantly making a bathroom just a bit more sophisticated.
Removing the walls and the closet if possible you will be able to create a lovely atmosphere that you are looking for. As you can see I’ve suggested using timber shelves which will accommodate the double vanity. On top of it would be good to see a mirror for your own comfort and also to bring more light into the room. The reflection from the window across will be strait into the mirror and the light will brighten bigger part of the room.
If you would like to bring even more light using LED, you could replace your existing lights with triple LED warm lights. Bathroom is a space where the light is very important and the warm light will keep the minimalist and clean look.
I hope my suggestions were helpful and if you have any further question or you need any assistance, please do not hesitate to contact me.
