Most of the comments where people have mentioned that it cannot be used for shower must know that this cannot be used for shower. It is a simple 3L geyser which heats up water quickly and fill that water in a bucket. If you leave the geyser on and pun on the tap on a slow speed, you can easily get full bucket of hot water in 8-10 mins. If you need continuous hot water shower, you probably need a bigger and costlier geyser. For a small family, this geyser is the best solution .
