I would imagine if you gave any decent tiler the option of having the skirting removed they would jump at it, am I right in thinking that theee are multiple rooms all tiled throughout, this would be near in impossible to set out without cuts and as walls are never true u would always have diffrent cuts at each side at least with skirting off u wouldn’t have silly wee cuts , I’m a fan of the old box skirting as this gives (approx) 35mm cover all round , but even with your skirting still plenty of cove 12 mm mdf ripped to hieght with top mould feature fixed to 2x1 rails top and bottom , prepaint mdf and mould , always great finish
