Pee’s in the Air
All of a sudden three weeks ago, the Internet caught fire with what seems to be its annual round of stories about urine in swimming pools.  As best I can tell, the story's current incarnation began with a March 1 report on the Web site of National Public Radio about research conducted by a group of Canadian chemists:  These folks figured out that they could

Double the Pleasure
Devising an approach to the application of fields of glass tile to complex surfaces is never simple, but when your goal is to do so while minimizing cuts and eliminating any visual "tics" that might stand out like sore thumbs when the work is done?  That's taking the work to a whole different level. The project under discussion here, built in Gilbert, Ariz., offered this sort of challenge twice - once in a large entryway waterfeature, and again in the backyard with an outsized
Iridescent Perfection
In my career, I've applied lots of fine finishes to swimming pools, spas, fountains and other types of waterfeatures.  Most often we work with glass tile, but we also keep our hands in a variety of ceramic or porcelain tiles, various mosaics and, generally, what most would call classy, top-flight materials.   No two projects are ever quite the same, but the procedures we follow are:  In every case, we at Rock Solid Tile (Calabasas, Calif.) end up having to work through imperfections in the concrete shells left for us by builders and their concrete crews - and that's true even if they're experienced and have
Warming to the Touch
Last time, we began a discussion of giving our clients the satisfying hot-water experience they crave with a review of basic design principles and coverage of a range of materials-selection issues.   Translating the good on-site positioning and great materials we surveyed in February into a luxurious spa experience requires the designer to have an advanced understanding of the technology at work in hydrotherapy as well as a grasp of the spectrum of options available to drive and control hot-water systems.    Before we address those key topics, however, it bears
Horses to Engines
When I first begin to do research for a column, I really have little control over the direction I might take. If it's a cut-and-dried technical subject where I'll be dealing primarily with solid, scientific facts, the task is relatively simple.  Using my own textbooks, two local libraries and the Internet, I look for my subject matter in a minimum of three separate sources.  If the information is identical in each selected source, I feel pretty confident that I can use the data in an article. It isn't always so easy, however, and that's nobody's fault but
