So pretty. I love your floor! I imagine a plant and a basket of bath towels in the corner, and a stand in front of the tub on the right side to hold some combination of soaps, book, drink, and/or candles.

Bench with upholstered seat to pull up to the tub to set your towel on or your drink. Paintings or pictures to match the upholstery on the wall and drapery. Table of some sort for mood lamps, candles, plants or toiletries. Make it jump off point for adding colour and pattern to the bathroom.

plant in a pretty pot.

Greenery is nice idea posted. Is there anything you're used to using that doesn't have a place yet [in this room]? or just somethings you might like seeing, and using by the bath... like a low storage with essential oil epsom salts [I recommend], battery candles...?

An elegant bar cart on wheels would provide valuable storage and soaking- in-the-tub luxury. Holds a few fluffy towels and fragrant soaps along with a cool beverage.

Beautiful bathroom!! How about a freestanding heated towel rack in that corner.

Beautiful so far! I would take advantage of that corner by placing a plant or three there on a nice plant stand or corner bench.
Good light from the windows, but do they give sufficient privacy? You may want to add light-filtering window shades or semi-sheer curtains for additional privacy.

A crown moulding at the color change would add a little elegance and definition…installing strip of lighting along the length of the crown…on a dimmer ….would be a lovely nite light…if this was my bath ….i would paint the upper area in a very pale aqua

I want this room and all the ideas with it! ha can't. I thought of humid room with metal on tile - can it eventually leave rust marks? I like this look with your lights, but not near the water!

Floor pattern, straight rods of the lighting - similarly strong lines of floral? or an orchid in a color you like.

A hook attached to canopy might allow it to hang fine from sloped ceiling. I like the look and shape of it, so I'll post it, though not for damp location - hangs down 22".

I like the olive tree in corner. Keep it simple and clean. Cleaning around that tub will be challenging.

Plant or bench. I’d vote for the bench so I could have my towel and stuff there. A teal one would add warmth. The bathroom is already great!

Beautiful bathroom, I like the idea of the tall plant in empty area and adding a bench for function..I would put bench on right hand side of tub opposite vanity.  Would put towel and candle on bench or lotions and bath salts, etc.

With light style? is the vanity like shutters? or flat fronts?

Or spikey maroon/ dark purple plant?

There are many directions art could take in this bathroom. Here are two looks. One spa like and one more artistic/chic look.

Bring in the accessories!

get a bunch of air plants and put them on a frame like this (easy to remove to spray them) and hang on one of those walls

I like the olive tree in the corner, or some of these hanging air plants, some wood shelves

this might be cool to do on the large wall. the vertical type of wall treatment, run a wood beam, textured light, and see if you can float a shelf for bath tub items.

or try the wood ladder in the corner, prop a plant up on a teak stool

dont forget a rug.

some texture would be cool

bring in some much needed color

Art for one of those walls is a must
