Hi Jane My recommendation would be to find a qualified plumber or tiler to complete this task. The key to a solid lasting repair is to make sure all of the old material is removed prior to refinishing the shower cubicle area. Be sure to check the reason why the grout has cracked, this can sometimes be due to the tiled surfaces becoming loose or moving over time. Also check for movement in the shower tray base, this could cause premature failure of your new seal. Spend good money on the product that you choose to replace the seal and tile grout. The grout will need to be suitable for use in a shower area. Allow the recommended curing times for the product before using the shower area again. Hope this has been helpful Kind Regards Lee Richards MCIPHE RP Water Trade Ltd
