What I can do to soak up potential leaks

Yes, you can take preventive measures to minimize water damage in case of future leaks from your bathtub. Here are some options: Waterproof Membrane: Consider installing a waterproof membrane or a waterproofing system beneath the bathtub. This could be a sheet of waterproof material that is installed between the floorboards and the bathtub. This helps prevent water from seeping through to the floor below. Bath Tray or Drip Tray: You can place a bath tray or drip tray under the bathtub. These trays are designed to catch any water that may leak from the tub. They typically have a slight slope that directs water towards a drain or an outlet. Sealing Gaps and Joints: Ensure that all gaps, joints, and seams around the bathtub are properly sealed. Use a waterproof sealant or caulk to seal any areas where water could potentially penetrate. Tile and Grout Maintenance: Regularly inspect the tiles and grout around the bathtub for any signs of wear, damage, or cracking. Address any issues promptly to prevent water from seeping through. Bath Sealant: Apply a bead of bath sealant around the edges of the bathtub where it meets the floor and walls. This creates an additional barrier against water leakage. Access Panel Installation: Consider installing an access panel on the wall behind the bathtub. This can provide easier access to plumbing in case of future issues, making it quicker to identify and address leaks. Remember to address any existing leaks promptly by repairing the cracked grout and ensuring that the surrounding area is properly sealed. If you're unsure about the best approach, consulting with a plumber or a professional experienced in bathroom installations can provide tailored advice for your specific situation.

Yes you can but the waterproof sheet under the bathtub and but silicon waterproof also and fix the grout regularly

I had a leak in my kitchen and after fixing the problem (obviously the most important part) I put a few ‘damp traps’ under the units to draw all the moisture out of the units and the wall, they act like a dehumidifier. It wouldn’t solve any future problems but does collect the water you can’t soak up for less than £10

I suggest you seal around the bath ,if there is a leak underneath the bath I’d rather see the leak in the ceiling below than have the bathroom flooded ! A leek on the ceiling below the bathroom it’s the first thing that can tell you there’s a problem underneath the bathtub
