Why not paint it in vertical stripes as that will make it look visually higher than it is , tiles will give it a busy look, its a Diy, you can use Masking tape .

Tile would be nice but because of the slope you'll find yourself cutting a whole lot of tiles. Have you looked into wallpaper? Or, you could paint only that wall a different color, like an accent wall.

What sort of wallpaper would be OK in a bathroom? I'm keen not to have to deal with nasty peeling bits in a few years.

Vinyl wallpaper for any wet or steamy area. To prevent it from peeling, use a wallpaper paste; don't count on the prepasted backing. You could probably use a vinyl coated wallpaper but you'll be happier with a sold vinyl.

I like the whitewashed, spare look you've got going now. I would change the surround around the tub to something that has horizontal lines or tile it with a beautiful stone. You can carry that stone onto the walls. I picture a soft, subtle marble in a cool neutral tone like the one below.

Tiling all the way to the top of the point is not a super optimal look, IMO, but it's better than stopping the tile at the bottom of the gable-end. For these reasons, I think it's important that the tile be subtle and similar in color to the adjoining walls and ceilings. You'll be essentially going for a texture rather than a color. It will look serene.

Whatever tile you choose (if you choose a tile), field size will be important. Try sketching out the simple gable-end wall and drawing groups of different sized tiles to see which one intuitively fits the space best.

The halogen lighting will look gorgeous in there too. I hope they won't be sticking out too far because those bulbs get so hot! I'd hate for you to accidentally brush up against them.

Best wishes!

AMN - What is IMO? thanks!

In my opinion

Oh! Of course. Thanks!

I would put white subway tiles around the room about 2/3rd up from the floor

I should probably mention that I'm on quite a tight budget, so high-end finishes like marble tiles are probably beyond my means. The bath surround has only just been put in, so I would be reluctant to replace it, also I want to be certain that I can get under it in the future, and tiling around it makes that difficult.

The halogen lights are going to be set in little recesses in the side wall to avoid burns.

Your back wall needs something that stands out, make it interesting. If you are, or if you have a friend who is an artist, perhaps something that speaks from nature, a tree branch, cherry blossom, or if you like something tropical. Nothing too complicated. A subtle splash of color to personalize your beautiful space. Good luck!

That's a good idea - I wonder whether I could reproduce part of a nice wallpaper pattern by painting and enlarged version on that wall? Anyone got a good pattern suggestion?

i wished i lived near you! i LOVE your house from what I've seen so far. I am an artist and would love to paint that wall behind the tub! You could just find a pattern or patterns that you've seen and project them onto the wall to see if anything appeals to you. A projector isn't that expensive and you could always sell it after you use it. IF you are using the green color that is around the tub, I personally love something in the periwinkle family. Maybe a pale blue-lavender color. It's a very happy and clean color to me. Don't ask me why, just is to me..

staying with your budget, if you want the wall in the back to do something special, maybe a nice stencil would help? Check out something like: http://www.royaldesignstudio.com. Paint is cheaper than tile.... that said I really like the yellow stripes.

I would tile the walls with some mini brick mosaics and finish it with matching chair rail.

Which walls, all of them? That would be pretty but rather expensive I would have thought.

It's shouldn't be expensive if you can allow 6 weeks delivery. check here: www.zapex.co

I don't know about stripes unless they stay very similar to the chose wall color. The room as is has a calm zen sort of feel already. Stripes might be a bit much for a space that should resonate a place for relaxing. Keeping it light and bright is already giving the room a chance to look large. Here is a simple mural - pretty, nice, you assemble it yourself. Costs only around $20 and comes in a few different colors. Just an idea. http://www.etsy.com/listing/99966125/cherry-blossom-wall-decals-white-flower . I think less is more when it comes to small spaces. Pick your favorite color and use it to accent other parts of the room like towels or decorative bottles, etc.

oooh I like the decal too. decals, stencils or stamps all would be inexpensive ways to work design into the space!

Vertical stripes might make the room look bigger......or look like a circus tent. With a diagonal ceiling line like this one it's a real possibility.

Right, I'm going to have to do some drawings I think. Does anyone have any recommendations for easy to use Mac software that will save me from the mandrolic option?

I would do to the corners not at the top and do it in flat white subway tiles. I am an artist and can envision things pretty well

Can you describe what you mean a bit more clearly? Where would you start and stop the tiles?

Here's how I see it looking with the basin fitted - at the moment the basin is still on the floor of the bedroom waiting for its frame!

I would go with a white iridiscent mosaic in the back wall and over the tub. I would paint the tub surround in a metallic paint, in a off-white and stain the wood floor white and then apply a heavy polyurethane coat. Add a zebra or leopard rug for zing and you have a glamourous but zen-like tiny but very functional bathroom. the white iridescent tile would give a little shine and the white/off white would bounce the light making the room look bigger.

I would stop the tiles at the bottom end of the back triangle from the roof

I would tile that entire back wall, as well as the toilet wall in a bright, happy color.

Paint the other walls bright white and find some great lighting, a mirror and a rug. That's all you need. Hope that helps. Charmean Neithart

Love your space! Have you considered wainscoting? Love the clean lines of it. It checks the 'vertical' box from a design perspective and mimics the exterior finish of the tub.

Looking beautiful! Love that tile color.

Wow! Gorgeous green, nice job! For your paint consider a white with a hint of lavender in it. Try Whisper Violet 2070-70 by Benjamin Moore. Bravo gingerclaire!

What a great bathroom color! Once you add the basin, try using a corner Lazy Susan underneath the cabinet to organize your toiletries. Good luck with the rest of your remodel!

Even better with grout! Come on, what to do for the colours now - I need to paint the T&G on the bath, the wall behind the loo and basin and the wall on the left. What should I do?

how about a chandelier added to this room. Make it more feminine. And also add few shelves to the back wall. Then accent that with a lot of candles.
