This is my treatment room

Are you able to get rid of the pink windows?

Before you talk about decor, I'd address the practical storage issues. Your shelves and drawers are a bit of a jumble and your overflowing trash area and bio waste is just a turn off. Are you considering new storage furniture pieces? Where else can your trash go and can you get a more attractive container?

Change the film color on the windows. Move all the storage to the side or back out of the view of the client. organizs and simplify the storage. Add art in the view of the client. Make sure the lighting is 3200k or 3500k for a warm feeling. Control the intensity as needed. Add music or green noise.

It maybe out of sight of the camera lens, but where is a sink? It is a must have to ensure proper hygiene.

I would clear the room, paint it a dark tone from the existing floor (looks like a gray or taupe color)

Cover the pink windows with window film

and install a tall storage cabinet (paint it the same color you choose for the wall color) behind your ring light/chair

Keep all your essentials behind you, on the door wall of the room so upon entering it looks clean and neat.

put your framed credentials behind you, visible, but not as featured art.

Leave the other walls clean and serene.

Have a sign company create a stick on logo/business name lettering of your choice.

Questions:

1. Can you post a picture of all 4 walls so that we can see everything that's in your room?

2.. What is the pink section? wallpaper? lighted area? glass?

3. Is the black treatment chair staying or can it be replaced by either another colour or bed type treatment table?

Here it goes with not much info...
