What is the best grout to use on shower tiles?

I've used the Mapei brand from Lowe's with great success. Just make sure you purchase the right one (wall vs. floor & for shower) then seal it.

When installing tiles in a shower, the grout is an ordinary Portland cement mixed with powdered pigments and water. Polymer additives ensure flexibility and color quality.

The two types available are sanded and unsanded. When choosing between these two types of grout for a shower tile installation, the only consideration is the width of the joints themselves. A tile joint is simply the space between two adjacent tiles, which is filled with the grout. Tile joints that are 1/8 inch or less need unsanded grout, while joints wider than that call for sanded grout. The sand keeps the grout from shrinking in wider joints after it is applied to the tiles in your shower. Be sure to cure the grout for at least two days, then seal all grout applications.

If you're choosing between sanded and unsanded grout, tile placement can be the deciding factor. If the tiles are very close together, an unsanded grout is probably best. But if the design calls for the tiles to be positioned wider apart, sanded grout is a must. Any tiles that you'll step on regularly should have sanded grout, as should handmade tiles.

Starlike Grout is a grouting product that can be used as adhesive and grout. It's sturdy enough to stand up to heavy-duty cleaning supplies, yet undeniably attractive and available in a total of 94 finishes.

Crystal Glass Grout® is a translucent grout made of tiny glass beads. This grout is especially beautiful for grouting glass tiles, because it reflects and refracts light. This creates a chameleon effect, as the grout either takes on the colors in the tile and enhances the beauty of the design, or remains neutral in color, not clashing with the color of the glass. Crystal Glass Grout is the simple and easy choice for glass tiles.

Another vote for Mapei grout! We're planning to use it for our next job.

Cheryl....I am no sure of the best but my daughter found what she liked and styled her new bath with her husband. They did have someone (professional) do for them but they gave the instructions coloring and it turned out so nice. The professional who did it was very pleased and said he thought it was the nicest he had done. In other words, pick out what you want and talk to your contractor. Good luck

The key to choosing a grout lies in matching to your tile spacing. Use sanded grout over ⅛" grout lines. Allow grout to dry for a couple of days and then seal it. This is essential!

we used a premixed grout with a sealer in it. Comes it tons of colors, you can buy it at home depot.

All tile places carry their preference to grout. I have used several and have no preference. If you are buying a tinted grout MAKE SURE you seal it with several coats of grout seal. It is tedious but worth the time. Soap will sink in and change the color making it chalky over time and you can't get it out of the pores of the grout.
