Yes, it's ok to shower with a silicone ring. Silicone is a waterproof material and durable material. Any soap and conditioner that are safe for the skin are safe for the ring.
However, it is important to note that some factors can affect the durability of silicone rings, such as exposure to chemicals, extreme temperatures, or excessive stretching.
Additionally, if your silicone ring is loose or damaged, it may be more likely to slip off or become lost in the shower, so just make sure that your ring fits securely before wearing it in the shower.
