hi. Have you tried swapping the shower and loo round? You may be able to go for 1200x800 shower and create a recessed shower. Alternatively go for the next size down if you want to create a niche in the wall for shampoo storage etc. I'd have a 600 wall hung unit for storage (being able to see the floor increases the sense of space). Are you tiling all over? Ask a plumber about a recessed shower as it will make it more streamlined but it depends where the soil pipes are and cost, practicalities of moving

Absolutely echo comments above regarding raising the soil level around the tree, a big no no as it will mean at best the tree will struggle and fail to thrive and will probably eventually die. Decking is a good solution if you want to install a seating area around the tree, with planting around it to soften the edges. I would maybe look at a composite decking as it will mean less maintenance and will not become as slippery as timber in a shaded area, also if going for a contemporary look it can look very sleek, especially if choosing a grey or even black. You could also add in some lower growing shrubs, herbaceous, spring bulbs etc and create a edge of woodland feel to this area, which would have interest and create a lovely view, whatever the time of year. What ever you do good luck.

Jonathandb1972, I was thinking of going with a grout that is the same colour or lighter than the grey tile. The hex will be grouted in a medium grey. This has already been done in the loo (the hex) and looks great. Neither are grouted in the above picture. Do you think there will still be issues with where the grout lines are if they are the same or lighter than the tile? Also, where the hex tile in the shower meets the grey tile will mainly be covered by the shower's profile. However, the shower only goes up to about 2m, so there will still be a visible "meeting" of tiles above that. My builder is a little concerned about how this will look as he will have to cut small pieces of tile to fill up the edge, which may stain once they start grouting. I'm keeping my fingers crossed and hoping for the best...

Yes some photos please :) Meanwhile: Limestone, slate, walnut, offwhite.. Bits of mother of pearl, bronze, satinated glass..
