Shaving in the Tropics
Santo Domingo, Dominican Republic
Hot water is an amenity that budget travelers often do without, especially in tropical climates, but a few simple items in your pack can offer some relief from a cold razor against your skin.
One of the most overlooked items to bring with you on your travels is drain stopper. Buy a large, universal, cover that will plug the variety of drains you will encounter.
Once you've got the water (in a bucket or sink will do), you'll need to warm it up. An immersion heater does nicely, and is typically sold as a single coffee cup warmer (for about $14 USD). For flexibility, make sure yours is dual voltage.
Often times there won't be an electric outlet in your (bath)room. The solution to this problem is called a current tap. This device sits in between a regular incandescent light bulb and the wall/lamp receptacle, giving you two outlets to plug your powerables into.
Lastly, a small extension cord is always useful to have. I made the short one I carry from simple items found at any hardware store.
With any luck, you won't need all of these items to fashion a sink full of warm water, but they're so handy, small, and light that I wouldn't travel without them.
