I want to divide an existing room and use the division for a bathroom, so the new wall will have a shower built against it but be non-load bearing from the top. I thought breeze blocks would be the thing to use. It will be 6' wide and about 8' high as we are going to put glass blocks along the top to let in some daylight, When I did a costing for the breeze blocks I nearly died as it came out at nearly £500. So, what do people use for this type of wall? Obviously not breeze blocks.
