When sealing showers, you will want to opt for 100% silicone sealant. Silicone is flexible and durable. It also repels water and moisture, which makes it ideal for high-moisture areas like showers.
While caulk is long-lasting on solid, unmoving surfaces, silicone sealant's flexibility means it lasts longer in areas with higher moisture. Using silicone sealant in a bathroom for sealing cracks in the tub and shower will create a more durable seal without needing to frequently re-apply.
