Since the TB-1 was ordered as a naval torpedo/bomber (see prototype page), it was natural to install it on floats and fulfill the original program. Talks about converting TB-1 to floatplane started on January 15, 1926. But practical efforts did not start until 1928, because team was too busy with trials and introduction of TB-1 into mass production.
In 1929 modified Junkers floats were installed on 'Strana Sovetov' for its record flight. But this type of floats was found unsatisfactory for mass use. In October 1929 the UVVS ordered several pairs of various size floats from Short (Great Britain). Those floats were made of duralumin with steel joints. Construction was very clean, trials at TsAGI hydrochannel confirmed high quality. Sample floats intended for 7-8tons aircraft were introduced into mass production as 'Type G' (see data below).

Results with TB-1P were good. Seaworthiness was above average, no problems during landing and takeoff. 'Type G' floats were in production in 1932- 1935, more than 100 pairs were assembled. Few dozens of TB-1 were equipped with this type of floats and served in military (as TB-1P, Poplavkovyj, floatplane) and as civil (under designation G-1).
