I would use the curtain for a while and see how it works then if you don't like it anymore you can replace it with a glass door later.

Hi cwcalaska, agree with R H Kitchen completely. :)

Frosted glass doesn't show spots as much as clear glass.

I am going with a curtain in my shower/tub for the same hard water reason. Curtain is easy to replace often.

It seems like a shower door encloses the tub too much. It's like taking a bath in a closet. Hard water just ruins the look of a shower door. Trying to have a tub and a shower just doesn't seem to work well.

Easiest is a curtain. I've found that replacing with doors, they get in the way. Difficult to sit on edge of tub to shave legs. Difficult to bathe small children. Much more difficult to clean the tub with doors. Curtains have so many wonderful fabrics and prints for change of decor.

My inclination also is to go with a curtain. Husband is resisting that! To clarify, the current tub (pictured) will be removed and replaced with a tiled walk-in shower. Thank you all for the suggestions so far.

If you stay with a curtain, I would hang them all the way up to the top of the ceiling -- like in model homes. Amazing how that looks.

I guess I missed the walk-in shower. Changed my mind, Doors but with hard water, it is a concern. Maybe frosted glass.

A curtain with a bow rod to make the area feel bigger.

How about this option? Glass, but no door? I think you would still have to squeegee the glass to keep the spots down. I used to have those sliding glass doors above the guest tub and removed the glass and put shower curtains. I like it MUCH better to clean and makes the space feel larger. PS. For our master bathroom, I'll be doing the walk-in shower with half glass and seat.

Glass door. Had one for years and loved it. Use a squeegee. Lots of safe cleaning products out there to keep it clean.

I've had both, and prefer shower curtains as they are easy and inexpensive to replace. Shower doors only look good when they are installed - not after daily use and squeeging every single time is a pain in the 'you know what'.

Frameless glass shower enclosure hands down! If his is a walk in shower, it will make the room look bigger. They have a product they put on the doors that repels the waterspots, Keep a squeegee in the shower and just wipe down when done. Shower curtains get water all over the floor, get moldy and yellow after a while. I personally would not choose to ever have a shower curtain.

Darzy, I have considered having glass only at the shower-head end, but the way our plumbing is arranged, that would mean the opening would be awkwardly placed beside the toilet. If I do go with a door, it won't be sliding doors. Ugh. The frosted glass idea sounds okay, or maybe some type of seeded glass - clear but with a textured appearance, if that makes sense.

Some shower enclosure contractors offer an option for Shower Guard or Vista Shield glass. It costs more than standard enclosure glass but it's maintenance is minimal. Here is a link to the glass mfr. and info regarding maintenance.

I took out the same set up as you have in the guest bathroom and did a shower only, these are the doors I put in and love them

cwcalaska..good point about the plumbing configuration. Is this the type of glass you are considering? "Rain" glass panels.

@Darzy- I looked into the one piece of fixed glass, the shower people told me you need a large area for it to work well or water will get all over. Have you been given any advice?

With hard water .....shower curtain yes. you can replace it often in comparison to a door .

I've dealt with hard water on a door. I hated it until I discovered the squeegee. No more spots. It only takes a few seconds to wipe it down after every shower. A frosted glass or crackle glass is more forgiving too.

We have very hard water and I installed a frameless clear glass shower door. The contractor said that the glass was ground completely smooth so that spots do not adhere to the glass. I do use the squeegee which takes about 10 seconds, but I'm not sure it's even necessary. I have no spots to clean off at all, ever. I previously had frosted glass shower doors that spotted constantly so it is obviously the new glass treatment that made the difference. Talk to people who actually install these and make sure you have the latest information, if your concern is spotting.

I dislike doors ,when we had one I had to use a toothbrush to clean the track ,no more doors for me :)

Check the warranty on the no spot glass. The company you purchase from should stand behind their product if it doesn't meet the expectations.

Thank you everyone for the ideas. The "rain" glass, Darzy, yes. And I didn't know about the Shower Guard glass. Definitely something to look into if we go with doors. Bathing children isn't a concern because there's another bathroom that has a tub (no doors!).

cwcalaska, interesting about the "rain" glass -- how do you feel about the "non-rain," uniformly frosted glass door ? :)

Ed, I haven't gotten as far as looking at actual samples. I guess it would depend on the tile we use and how clearly or not we want to see the color. If we go with doors!

I put a coat of Rainex on my glass doors and keep a squeegee in the shower. Never have a problem with spots.
