bi fold bathroom door

I don’t buy pre-made furniture. I’d make the door using the appropriate flush hinges and fit.

Bifold doors will always have gaps for hinges to bifold, Also Pelmet can be fitted inside bathroom, This can be rectified by purchasing Self adhesive draft seals from Screwfix or Trade point & fit to both doors on hinge sides & frame to seal gaps for privacy Doors can be purchased from Howdens Joinery & Magnets Trade & B &Q & many more Hope this helps MG Carpentry Mike

Don’t buy a by fold door their not very good quality and the runners don’t last very long

Howdens and Wickes both sell fairly good bifold doors, they are made to fit standard openings and come ready hinged , complete with track and guides, You are looking at around £60 Hope this helps
