I have a bathroom upstairs. It recently developed a crack in the floor. When ever someone uses a shower the water is sinking in and leaking through the roof. The bathroom floor is made from laminated wood planks. Suggestions needed.
What type of shower do you have in the upper bathroom? Is it a one-piece fibreglass stall, constructed in place tile shower, bath tub with shower? More info is needed.
sanitred or something like that,,, if its a tub, you may get some callouses on your hiney but its lots better’n ruining the floor,,, ‘sides, its only temporary til you can get a pro ( plumber or tile guy ) in to fix the trouble.
