Could you post a pic of the whole space I would look for a glass shower screen that curtain makes the space look even smaller than it is

I agree, posting more photos would help. If you are on a tight budget, first try painting that mirrored cabinet to match the walls and getting nice metal or ceramic towel bars. I see a ceramic towel bar in the shower stall, a metal toilet paper holder and a wooden towel bar..you want a more consistent finish in such a small space. A Lighter colored shower curtain would also be an affordable step in simplifying the look of the room.

This bathroom is smaller than small if the sink is literally touching the toilet. I think you will have to change both fixtures to a more sleek, narrow, modern style to keep them visually and physically separated. I would consider placing a sink in/on a narrow vanity cabinet to give a small amount of storage (unless there is some adequate storage elsewhere in the room).
A glass shower door will allow the space to "feel" larger, but the placement of a glass separation wall next to the sink will make the space too small to even brush one's hair in front of the mirror unless the people who may use this tiny bathroom are all left-handed. You may be better off with a shower curtain pulled forward to give a little arm and elbow space for the occupant.

I would look for a glass shower screen

Agree. While I like the color, it seems to be touching the sink -- and that makes the whole thing look really crowded. The glass shower screen would sit ON the edge of the tub instead of to the left of it, which would give you a few inches of elbow room.

I agree that in such a small space all-white would be a good choice ... but do bring in some texture or tone-on-tone white so it won't all look "flat".

What I would NOT do: I would not lose that pedestal sink. No, it doesn't give you any storage, but in such a small space, a cabinet would be overwhelming visually, and a cabinet that size wouldn't hide anything more than the plumbing.

paint the wood to white and have a full width shelf ( white floating or glass ) on the grout line above the sink for the stuff and keep the things off the sink and toilet tank.

Agree again. Having one single wood-tone item looks odd -- looks like it was a mistake, and the fact that it's a wide-chunky frame just adds to the problem. So, yes, paint the wood white ... or replace with something frameless.

What I like is that you have a BIG medicine cabinet ... in this small space, you surely need the storage, and one item works better here than a cabinet and separate mirror. Is your medicine cabinet DEEP? They make them 6" deep, which would allow you to store full-sized shampoo bottles in the cabinet.

I also like the idea of a glass shelf to hold your "instant access stuff". The clutter on the toilet tank and sink do nothing to help the room. The glass would also echo the glass shower screen.

you want a more consistent finish in such a small space.

Yes. Do you need storage space for towels? If so, I'd put a train shelf UP HIGH at the end of your shower.

Your four-bulb light fixture seems to be oversized for this room. I'd downsize to a two bulb fixture (I'm assuming you also have a central overhead light). I think it'd make a difference.

I don't know how much you're looking to spend on this reno, but let's talk tile. The gray isn't bad, but white would be better ... if you're looking at replacing the tile, I'd go with a creamy off-white tile in a SMALL SCALE (couldn't find an example of a sink with white small tile). I think it'd put things into better proportion.

I'd love this tile in your bathroom ... the bit of shine would add a lovely touch in such a small space. I'd like it even better if it were more of an off-white creamy-white.

Here's a nice overview pix of what I think your bathroom could be. Although everyone here seems to be preaching "all white, all white" ... I like that this bathroom has a bit of black on the floor; it keeps things from being entirely monotone and sort of "grounds" the room.

Thanks everyone!

There's not much more to the bathroom...You can see what little is left to it in the mirror. The floor is white linoleum with grey flecks.

So the quickest fix would be a lighter shower curtain and a white towel. It sounds like the consensus is to paint the cabinet white, along with the towel bar? Probably the hooks seen on the door in the mirror too? I think the baseboards are oak-colored also, can we keep those unpainted?

I'm not sure I understand why the clutter would look better on a shelf than on the sink; toothbrush and paste can go in the cabinets. Then we'd just have soap dispenser and a decorative soap on the sink. What if we got the cube-shaped kleenex; would that and the 2 jars still be too much on the toilet?

I see now the sink is too big, maybe we can think about that down the road.

Below is an image from the same bathroom layout, but flipped. Even though the tile is dated I felt like they'd worked with what they have better but I didn't know why. Thank you again everyone with the good eye for these things.

I think the bathroom above is an optical illusion, but the two biggest differences is a lighter shower curtain and the white storage unit.

I think a smaller light bar would be the one new thing I would purchase. Get rid of all natural wood...paint the cabinet, towel bar, door and baseboard white. I really don't like glass tub enclosures, so my suggestion is a light shower curtain.

Okay phase one! White shower curtain.

Much better curtain. I think the major issue in the space is the huge cabinet and light fixture. I would suggest replacing with a small mirror over sink with small light fixture above and a small corner cabinet in left corner.
I think that's what you are seeing in the other bath picture you posted that you said looked better to you.

The first thing I see is the obtrusive medicine cabinet and lights. It is way over sized for the space. I have lived with an oversize cabinet for years and just ordered a recessed cabinet without a frame. I anxious to take back some real estate.
